I've now gotten Bluetooth proximity working. It appears the xPL-bluetooth code isn't right so I've made my own changes and now it works. Also, after installing mpg123, the dock is now an MP3 player. It was using about 50% of the CPU and sounded pretty bad until I found this post. I made the suggested changes and the CPU utilization dropped to 2-3% and it sounds just fine. I also installed the Squeezebox emulator Squeezeslave (there is a native binary) and it works great. I can stream last.fm to it, but Pandora refuses to stream to Squeezeslave (a old, known issue).
