You really haven't done your homework about Renderosity, have you?

Let's try an experiment: let's say tparo was a vendor (apologize for using your name, but since you've been following the thread I figured you wouldn't mind)

They make a dress for G3F and want to sell it through Renderosity. Now since this is for G3F the format is .duf, not .obj, but say there is a way to encrypt .duf's.

Tparo encrypts the file and sends it to Renderosity. Now the way I understand the Marketplace is that EVERY CUSTOMER GET THE SAME FILE, which means all the customers that buy the dress will get the same encryption key..

Now let's say 1000 customers buy the dress.. tparo now has to keep track of 1000 different customers, their IP and their different computers.. how exactly will this help them? Sounds like a full-time job to me..

You simply don't understand the scope of this Marketplace, the top vendors can sell hundreds and hundreds of each product, multiply that with how many products they make and the total of legit customers they would have to keep track of.. do you see what I mean?

I'm sure you mean well with your business, but this is the wrong market for it..
