Not really, it depends a lot on your soundcard. Certain drivers can
support several playback channels. I thought a while back I heard about
some work going on to make this possible on any soundcard through some
kernel level sound mixing (this is possible today on FreeBSD using the
commercial OSS drivers, but I'd rather wait for FreeBSD's drivers to
support this) in FreeBSD but I'm not sure what's going on with it.

Right now your only options to do this are use esd or use arts (arts is
part of KDE2, and esd is usually use by gnome) and then use esd and gnome
enabled programs. Almost everything supports esd, so you shouldn't have
any trouble finding them..
