One could envision usage of POSIX ACLs.  Very hackish, but some daemon
could add an ACL entry to various files in /dev when a user logs in,
or logs out, or time passes, or some device is plugged in, or
whatever.  No need for special groups.  Of course, maintenance would
probably be a nightmare, unless there's a way to share ACLs between
files that I'm not aware of.
