Anyone may contribute. Announcements are made on freshmeat.

Yes. Fully RFC2250 compatible.

Not at this time, but we are very interested in it. Tests show that
MP3-ADU framing gives really good results.

Not at this time, but this is planed.

RTP:
  freeamp works without plugin (Linux)
  mpg123 used with the provided dumprtp (Linux)

HTTP (using nph-unicast.cgi on a web server)
  freeamp without plugin (Linux)
  xmms without plugin (Linux)
  winamp is also reported to work (MS)

Plan: release a full GPL audio/video streaming solution.
