Hi,
As you probably are aware of, there is already a wap interface (
http://yourhost/subsonic/wap). However, there is no way to start streaming from that interface - only playlist management.
If you have a streaming-capable player on the phone, you might try typing the URL directly in the player (
http://yourhost/subsonic/stream) and see what happens.
I am, however, planning on implementing one or both of the following:
1. Adding an option to start the stream in the wap interface.
2. Implementing a new lean html interface suitable for presentation on phones and pda's.
