Here are some other options for media server with Android player. I'm looking into them, so haven't decided which I like best.
Subsonic:
Subsonic » Free Music Streamer
Audiogalaxy:
Audiogalaxy. Your Music. Your Playlists. Hit Play from Anywhere.
Twonky (no Android player yet, but should be one coming):
http://www.twonky.com/
DAAP Client (choose from a variety of DAAP server to serve to it):
daap-client - Project Hosting on Google Code
