Ahoi,
as some of you already realized, project Ropefall has closed doors. This means no new licences will be given away.
Maintenance support will remain available in the maintenance period (a year after purchase).
Thanks for your support so far!

Projector cabling...
Thanks Kwin for the awesome pics!! 
Dan, thank you for the your comment! I answered it in the bug report, I suggest we continue the discussion there.
Thanks a lot for your feedback.
I am planning to build a more sophisticated licencing system but it is a non-trivial task and takes time to develop. Or maybe I go with SU's licencing system in some future release, we will see.
For now, we have to live with this simple process. Please just drop me an email once you need a new key within a year after purchase.
Hi Guys, thanks for reporting this.
The licence is valid for a single Ropefall installation, it does not expire.
So if you install Ropefall on a Sketchup 2015+, successfully enter the licence key purchased and do not change or modify anything in your Sketchup environment that makes the licence key invalid, then you should be able to use that Ropefall instance forever.
So what change can make a licence key invalid?
In these cases please contact me at ropefall@sketchrope.com and I will generate a new licence key for you, free of charge within the one year maintenance period.
Does this help?

Dave made some investigations which got deleted by moving this thread to the developers forum. I give here a short summary of his findings:
Dave, thanks for looking into this!
I uploaded the skp (created by commenting out "face.followme(edges)" line in the script above). Interestingly, Sketchup can use the FollowMe tool normally if I use it manually on the model (select the line -> select FollowMe tool -> select disc at the end of the line). There is no bugsplat report in this case.
The issue seems to arise when FollowMe is run over the API. And I checked the edge lengths : none of them is less than 0.001 inches, the smallest being 0.0031780318151616855 inches. See the list of edge lengths below.
Thus the situation seems to be different from what you describe above because:

FollowMe works even without scaling up when using it manually over Sketchup UI. It chokes only when calling it over the ruby API.
Some more background: some customers of mine detected this issue when using my Ropefall plugin. So the obvious (already known) workaround is to only draw midline of the rope with Ropefall and use FollowMe manually around it.
To implement your scaling workaround in the plugin is hardly viable since it is hard to guess how much scaling would be enough.
Also, I think the right place to fix this is in the core product. Sketchup should handle weird wire shapes in a graceful way, it should never crash. At least not when the API contract is respected (I mean the script above uses the API properly, yet Sketchup chokes on it).
Please note this example is an artificial one created for reproducing the issue - that is why it has such garbage near the end of the line. The first fixed segment is vertical, which is hardly ever the case in realistic uses.
Any opinion on this maybe from the Sketchup team would be highly appreciated! Thx!
Also, is there any developer platform for reporting Sketchup issues? I reported this over bugsplat but i could not send the script reproducing the issue in the bugsplat form. Thus some bugzilla or jira reference would be nice to file the bug report properly... 
I found this this discussion: https://sketchucation.com/forums/viewtopic.php?f=180%26amp;t=16734
TIG says:
@unknownuser said:
SketchUp's FollowMe tool fails on paths with short lengths where the faces it would make on the innermost part of the turns very small.
Do we know what the exact condition is that the curve needs to fulfill for the followme tool to succeed?
If this one is indeed a Sketchup product issue is there a chance sketchup team looks into this and fixes it? 
Hi there,
follow me tool makes Sketchup (2016, 2017, at least windows) choke.

There is no deactivate option but I create you a new licence key for the new machine within the one year maintenance period. Please send me an email! Thx!
Collage,
thank you for your purchase, I have just sent you the licence key to your paypal email adress. Sorry for the delay. The Ropefall purchase process still involves a manual step, namely signing and sending out the licence key, that takes place within a businesss day after purchase. Now you have the key, please contact me at ropefall@sketchrope.com if you encounter any problems with it.
The licence key is technically bound to a single machine (and OS user), thus your key only works on the machine you initiated the purchase from. Nevertheless I am happy to send another key to you for your other machine. I will contact you regarding this.
happy roping,
Balazs
Thank you Collage!! 
Come on guys, keep these cool pics coming!!!
I am eager to spend part of Christmas holidays to put Ropefall to the next level -
I need your input which way to go!
Would you like to see new features or performance improvement? Some comments on this along with a picture depicting what you use Ropefall for would be most helpful! 
ps. is there a way to get notified via email about new posts in this topic?
Solo, thanks for the feedback.
The speed depends mainly on how complex the model is underneath the rope sketch. More precisely, underneath the upper X-Y square of the bounding box around the polyline. So you can speed up roping by temporarily hiding model parts in this volume.
What do you mean by "this plugin is limited to a single rope"? You can draw as many ropes as you wish, see Massimo's example pics above. So whats your plan exactly?
well, at least you can use it as a reference and show your work made it to production. But there are these Creative Commons licences to have some control on business use...
wow... why can't I do that?
