One last question....Did you figure out the method of ruby integration through some documentation? or did you simply poke around enough?
I guess if you are already familiar with he inner working of Ruby at the object file level then you would already recognize some stuff you'd find in Sketchups directories.
I was learning the sketchup API as a reason to learn Ruby >.<.
Anyways...thanks a lot for the treasure trove of information you've just presented me...now to do something useful.
