It should be fairly easy to add another transport. I added TCP/IP
support in an hour or two (though it's very similar to the unix domain
socket). I figure there will be some more work with the X11 transport.

Tunneling over SSH isn't X11-specific though and I can't see why you
shouldn't just as easily tunnel your TCP/IP transport the same way.

As for D-BUS it sees no difference, you just use another transport. It's
in GPE the difference will be since you'll have to setup an external
communication if you don't use X11. Shouldn't be too much work to change
it later though.

As for firewalls blocking everything _but_ X11, is this really a real
life situation?
