Useless, since different distros use different runlevels to mean
different things.

I'm not sure why you would need to know this and I'm not honestly even
aware if there is a userland flag to indicate this.  Maybe you could
parse it from the "uname -a" output?

You can probably inspect Gdk.Display.Default.CorePointer to determine
these values.

This depends on what you mean by "is there any network".  You will have
to clarify this point.  Do you mean "user can reach the Internet," or
"user has access to something except localhost," or "the kernel supports
networking," or...

You'll have to be more specific about what kind of information you want.

I assume you mean rotation and not simply portrait/landscape (which you
could infer from the resolution of the default screen).  I'm not aware
of any GDK mechanism you could use to obtain this.  You would have to
query the XRandR subsystem directly.

Determining if the user is remote is problematic.  Services like
vino/x11vnc can operate alongside a local user, so there is no way you
can make the determination in those cases if the user is remote or local
-- there could very well be both a local and a remote user.

The only way you could say for certain is if someone were using a server
like Xvnc, which has no local display at all.  And there's probably not
a foolproof way to determine if the current server is Xvnc anyway.

If you want to know the Samba domain, you will have to query Samba.  The
*nix meaning of domain is very different from what Windows calls a
"domain" (a term it has hijacked to mean something very different from
what the rest of the world calls a domain).

The display size will be the size of the actual display as far as X is
concerned.  This means that it will encompass the resolutions of all of
the screens attached (so if you have two 800x600 monitors arranged
horizontally, this would be 1600x600).

If there is one screen and that screen's resolution is smaller than the
display's resolution, then that would qualify as a virtual screen by
your definition.
