I have been using the same device for different users.
(The trident driver, with alsa and OSS emulation.)
This device is supposed to do hardware mixing, so
several processes/user may use the same sound device
at the same time. Provided, of course, that they are next
to each other.

This usually works fine, but in some cases one user gets
strange echoey or chopped-up sound.  A driver bug/limitation
I guess.

The card supports front and rear speakers, perhaps that can
be used to provide independent stereo without having to
use more cards.
