We need a way to be able to rent virtual sets. Hollywood's probably already doing it. Grab a professionally set designed spaceship interior, 1950's living room etc. with all the little touches, the ability to add your own custom textures etc. for fee less than buying it and less hassle than running around looking for pieces. Technical challenges and may not economically viable but it would be cool.
