@Parellelus, good points, and well put.
I’m sure Envato is not only aware but probably discussed this topic many times in the past. If it’s not being worked on right now, I have no doubt it’s on the agenda . These guys are usually 2 steps ahead and I’ve been impressed by their forward thinking business style, solving problems before they become a major issue.
I actually brought up a similar point (in the vein of making it easier for customers that want to be able to go beyond the basic licensing terms), and Drew mentioned that Collis & the gang are having a meeting on this: http://codecanyon.net/forums/thread/any-update-on-multiusedeveloper-or-volume-licenses/54130?page=1#494192
Not sure if it’s already happened, but this would probably also be a good topic for them to discuss at the same time.
I guess the trouble is just striking a balance between flexibility (different licenses for different situations) and simplicity for the customers (i.e. not required to digest legalese).
