I agree with you about keyboards Gaieus, I have a french one and it's a mess sometimes. Concerning the < and > I meant the buttons on the interface, not the equivalent key on your keyboard.
I've just updated my web site with many more information about PhotoSculpt Textures plus about 70 images and free seamless textures.
Go to:

Let's discuss?
Hi Guys,
my name is Hippolyte from http://www.photosculpt.net
I'm new to your forums and many thanks to Pilou and Mike for the multiple invitations. 
I've used sketchup a lot last year. I'm a total fan of this application. 
I'm a design engineer, I know also most mechanical CAD packages (Catia 4&5, proe, ug, ideas, etc) and Sketchup blasted me as it was so userfriendly in comparison. I never thought this would be possible to design something that cool. Good job devs! 
To your questions :
Mac version: I'm sorry that's not possible now. I'm working full steam on the PC version. If this version work, they maybe I'll work on the mac version.
Price question: I'm doing a market study, that's really too soon to reply. Let's say I want the price to be 'normal'. Gaieus is right, what is 'normal' in every user's mind? That's a mystery now.
low/hi polygon extraction is a feature of PhotoSculpt.
Pressing the < > buttons on the PhotoSculpt interface divides or multiply model size by 2. You get immediate feedback on screen.
Additionaly a friend of mine have requested the 'save multiple' option. So you can now save whatever multiple polysizes with whatever maps in one go.
Archaeological use: That's a very good question, I have contacted people that work in this domain, I really think as you do Gaieus that my software can help them documenting findings in 3D. Some of them actually do that already. Some are using high end lasers, other use cameras and beamers to project bars, but they usually all describe something really cumbersome and expensive.
On my side I have made some experiments on the site of Plagne, France, close to Geneva, where they recently spotted dinosaur foot steps. I got wonderfull results in no time as I shot the entire site in 12 minutes (about 50 shots). I can share that.
to Jolran: you seem to have a lot of expectations about PhotoSculpt. You or anyone else please don't hesitate to send me your wish list, I may not be able to do everything, but just keep asking, that's really the only way I can make the soft improve.
Any other question? Please do not hesitate!
Now my questions about sketchup pro, can someone help me?
