Consolekit is exactly for this purpose; tracking users, logins, and
seats.  You can read a little bit more about it at
http://www.freedesktop.org/wiki/Software/ConsoleKit

It reports all of this through modern mechanisms; dbus.  Basically any
interactive (local or remote) session will invoke a console kit session.
This is why you'll see things like SSH listed in it as well as X.

ck-list-sessions is actually a wrapper tool around it's dbus interface.  It will show you lots more information than you probably care about, but it can certainly tell you whether a user is logged in or not.  That tool itself might not be well documented, but that's because it's output is pretty self explanatory.  You can read it's code here to understand more if you're a bit confused still:
http://cgit.freedesktop.org/ConsoleKit/tree/tools/list-sessions.c

I think the best thing for you to do though is read the documentation.
The DBUS api is documented there and you can take advantage of it.

Title:
  who -q no longer counts gui users

Status in “mythtv” package in Ubuntu:
  New

Bug description:
  The "checklogin.sh" script on this page: http://www.mythtv.org/wiki/ACPI_Wakeup uses "who -q" to determine if a user is logged in to prevent MythTV from shutting down the computer when a user is using the computer.
  On 11.04 this worked fine.
  On 11.10, my system shuts down 10 minutes after booting unless I open a terminal window.
  On opening a terminal window and running "who -q" I get:
  $ who -q
  dpeale
  # users=1
  I used to get "users=2". The gui user is not counted anymore.
  This is true of both Unity and Gnome GUIs

  The 'w' command also has the same bug (I've never been able to figure
  out what package that comes from). It also has another bug. If you use
  one of the ctl-alt-Fx screens, login, and then logout, it continues to
  count that screen as logged in.
