Android is starting to have some pretty cool audio apps these days, such as Rhapsody and MicroJam. Also the dence size of the SD card makes the phone an increasingly central place to store your mp3 collection. Because of this people will more and more be wanting to use their phone as a music source. Personally, I like not having my mobile devices wired to my stero by way of 3.5mm plug to the head phone jack and think it would be very cool for the phone to naturally be a wireless music source. Technically this is what an Android app would have to do 1. create a music server using some type of standard (shoutcast for instance) 2. loop the Android's system audio output to the streaming server's input Have either of these technical requirements been achieved yet in an Android app? And secondly, are they even possible? To accomplish #2 the app would have to have access to part of the system.
