Hey, I'm on a twitter network called "Game Developer Network" and they have really wanted to do an accessibility/audiogame themed game jam, not at the moment but in the near future. I'm way too busy to provide direct support though, so I thought that collaborating with this network would be a good idea. It might be a good opportunity to have indie devs experiment with audio game dev.
Their twitter network is here: https://twitter.com/GameDevNetwork_
Let me know if anyone is interested.
