Can I run a second KDE session, as different user?

My system has a group 'audio' in which all users + root are members.

Extract from /etc/group 

The /dev/dsp* files have the following ownerships and permissions:

crw-rw-rw-    1 root     audio     14,   3 Mar 23  2002 /dev/dsp0 

Perhaps these settings will do the trick.
