There's actually been some work going on on giving each user their
own /tmp namespace via the kernel's CLONE_NEWNS capability and a PAM
module, AIUI.  To the system administrator this could appear
as /tmp/<username>.  I think the problem is in getting later mounts to
actually appear in the cloned namespace.
