This is slightly tangential, but it seems Kickstarter has elicited some very good behavior from Double Fine--the game is to be DRM-free and will support Linux! I really want to see more games embrace both in the near future.

With that in mind, I wonder if Kickstarter could be the model for open source games in the future. Of course, getting people to pledge for a game that will end up free may be tricky, but I think it would be doable.
