Some months ago, I have done exactly this (I've played with D-Bus
tubes). It did work already to some extent. It shouldn't be too hard to
find my old code, and to commit it to the Emacs trunk.

Thanks for the hint, I'll check.

At least we are now two who want to connect to alternative buses :-)
Best regards, Michael.

I've just committed some patches to the trunk which allow accessing
alternative buses. If you are interested in, you might try it.

I reset this by
dbus_connection_set_exit_on_disconnect (connection, FALSE);
Best regards, Michael.
