It does seem difficult within the context of X11 to
prove that a user
is actually local to the machine. Some people may want to cluster
audio systems on a LAN somehow, so that restriction may not always be
agree. for most of the graphical applications like ardour, the
assumption "local user <-> realtime user" might be correct. but in
general i don't see the advantage over the group solution. their
might be local users on a machine which should not have realtime
privileges.
Careful system administration can probably ensure that
only a small
group of users are authorized to login. One of the things I like
about the `audio' group approach is that it is easy to administer and
simple to verify who has access to those privileges.
i think, that's a clean solution. to be able to distinguish between
realtime- and non-realtime-audio users, i'd propose to use a separate
group (e.g. 'rtaudio'), so
(5) introduce a group 'rtaudio', whose members are granted realtime
privileges.
on a multiuser system, i think it's not necessary to grant realtime
privileges to every user who wants to hear his custom system beeps :-)
