I would throw out another idea: A kickstarter for fixes/upgrades to the program. I would contribute, but I don't want special access for the $. There are few enough people in the community, why would you want to slit them into further smaller groups???
Tell us what it would different levels of fixes would cost and lets see if the community can raise the $.
Actually this is a fucking great idea. I would contribute with 50 dollars for my main game coming back to my HD.
