Mmmm... I managed to play stuff simultaneously by using esd, and I just
stuck to it coz it was easy to setup, but there are other options, like
the art one that Thomas mentions.
I mean, not that I listen to many things at the same time 8-) but it is
quite useful to resolv the greedy xmms paused in the background while I
hit the bed watching a DVD with my recently compiled mplayer
(Thaaaaaaaaaaaaaaaaaaaaaaaaaanks to Christian ;-)))))))). So, just give
it a try... it works with ALSA (my system), and it works with most of
the programs around (there is usually a plugin or something to play with
esd).

My setup works with ALSA... do you mean that it might be possible that
ALSA puts such a layer for multiaccess the sound device without running
a daemon? Now, that would be cool :-)

P.S. BTW, anyone know of any way I could play a movie remotely in a
server, and listen to the sound locally? Coz if I export an X
session, then, the movie is played on the remote server and I can
view it in the terminal, but the sound plays in the server! If I
could "stream" the audio, then I can use an old laptop to watch
DivXs from another room 8-)
