I don't think sound servers are going away, rather they will use
snd_pcm_open to go through dmix or hardware mixer instead of opening
(and potentially blocking) /dev/dsp.  The traditional sound servers are
useful because of the minimal amount of code required to do something
like "play this wave file".  The major remaining drawback is latency;
click on button in app, hear sound 2 seconds later when scheduler
finally chooses the sound server and it gets swapped back in.  It is
also rather stupid that GNOME and KDE utilize incompatible sound
servers.  aRts feature set is a superset of esd's feature set, so it
seems sensible for both environments to make use of that one, or to add
a sound server specification to the freedesktop.org standards.

Maybe a better thing to do is rewrite arts/esd library interfaces to
omit the daemons altogether.  That way the daemons can go away, but the
existing applications can be trivially migrated.
