this would be extremely complicated. and thats why it wont work. there were like thousands of tries to make one mass project. they all failed terribly. believe me, i joined one of those at 3dgsuv.com (i think it was called the fourth seal or somethin like that), the organization went well for a few days, but after that, nothing happened anymore.

if you want to try it, so do it. but be prepared for epic fail.
