DBUS wasn't designed to allow this sort things. Although non-trivial,
it is technically possible but brings a bunch of security issues and
requires programs to run on both sides (the user and root in this
case).
It all boils down to socket bridging and port forwarding. There's a
tool that would do that automatically for you (can't remember the
name), but you can achieve that with socat and the likes too.

I'm not trying to say that this is what René should do, I'm just
saying that it is technically possible, for the sake of correctness.
