Don't hate me for saying this guys because I am happily patiently waiting for V3 like (most) of you, but I think it would be awesome if after V3, Max considered releasing it as an open-source project moving forward. Since he is the only dev working on it (I'm assuming thats by choice, some people just prefer to work alone) I am sure he is the kind of guy who would hate to see his "baby" forked and picked apart by various people but it would be so awesome to see an open-source version of PA that had community-based development, modifications, etc.
The guys over at XDA would have a field day Heck someone might even figure out how to pipe V4A through PA so V4A doesn't downsample to 16/44kHz. Wouldn't that be amazing?!?!
