I think that static scenario was not the initial purpose of VWD. I had plenty of discussion with Gerald for "us" who want to use dynamic simulation to improve still render and what we need. I don't know what are the differences between the demo version you have and the complete version I have but I can say to you that there are plenty of amazing possibilities. The last videos about adjusting clothes, elastic parameter or collision offset,... are perfect examples.

I read that copyright protection discussion was about the complete version activation process (key,...).

There are no miracle :-) but I must say that VWD is worth every pennies, dollars, euros,.... and I get nothing from VWD saying that!
