Can someone make an app that streams what iTunes is playing to our phones? We could then have our own remote speaker systems (i.e. play music on our speakers without any computer cables)

I would pay to have this kinda application and it would truly be awesome

Ive tried DroidTunes but it runs on WiFi and the latest beta seems broken (Ive read that it works for some ppl but their instructions didnt help and it kept crashing). I am thinking it would be possible to implement this kinda app without any Server application running on our computers since we have these A2DP and AVRCP Bluetooth services(?)
