And that top layer should take low-latency into account. When you are
playing a mp3, if it is delayed of 400ms, you won't hear it, if you are
using GnomeMeeting and that the remote is delayed of 400ms, the
conversation will become hard to follow.

GnomeMeeting CVS has native ALSA support. Using dmix creates a new fake
soundcard usable by all programs. The sound would be mixed between all
those programs using the dmix fake soundcard, but all of them need to
use it. Yes, that would work with GnomeMeeting.

(Notice I have never tried myself though)

CVS is able to use OSS, OSS emulation, or native ALSA.
Release version is only able to use OSS, or OSS emulation.

In a few days we will have packages for the CVS release with plugins for
nearly all distributions.
