ssh forwarding for dbus is sorely needed; ideally working just like the 
X forwarding stuff I would say, to minimize confusion. I guess that 
requires patching openssh, though?

including an ssh transport in dbus would be almost as good except 
DBUS_SESSION_BUS_ADDRESS still has to be set manually on the remote 
machine. Still, I would think an optional (configure --enable-libssh) 
ssh transport is interesting if we assume we can't patch openssh.

You would ideally use ssh itself for authentication, rather than any 
existing dbus mechanism. This will require introducing a new dbus auth 
mechanism that might be like:
  client: assert that I have already authenticated via ssh
  server: confirmed
