Lots of people use apps like qik or ustream to stream video from their phones. Sometimes at larger events bandwidth is scarcs, it would be nice if an HQ audio-only stream could be streamed to a shoutcast or similar server
ideally the app would:
-take a line in/mic in with some sort of level indication, to the limits of the mic in hardware
-compress to selectable mp3 bitrate on the fly (160-256k vbr LAME)
-longshot: support for sony bluetooth microphone ( i dont know want sort of bt protocol this would require)
