However, the reasons for it are really not that good: we _do_ have a real user, and things like home directories typically _aren't_ flushed on each session termination.
But we don't have a "real" user on the thin clients, the real user is logged into the server, not the client, so that doesn't help us, since PA needs to run on the client for it to output the sound. 
If you were doing DRBL, where you network boot the OS, but all the apps are actually local, then system mode doesn't make sense, but you still need it on thin clients, since the user's session is actually on a different machine.
