I will be at Linux Audio Conference for the rest of this week.  The
conference will be streamed to the ‘net’; if you look at the LAC site
http://lac.linuxaudio.org/ and a click on “Streaming” will bring you
to this page:  
http://lac.linuxaudio.org/?page_id=29
which has all the stream info and the IRC channels on irc.freenode.net:

  #lac2008 for the current track
  #lac2008-tech for stream-related issues

One can ask question of the speakers via IRC
I have papers on Thursday 12:30 (A Blues band) and Saturday 17:00
(Sliding Discrete Fourier Transform), and a piece in
the concert Thursday evening (not icecast); also apparently on the
panel Sunday 13:00 – 14:00 about “Maths Rocks”.
