The problem with that is that it implicitly changes the scope of the
bus to per-homedir (which may not even be per-machine, due to NFS or
AFS).
Then two sessions end up talking to the same gnome-panel, things like that.

For things to work exactly as intended, ssh should forward
DBUS_SESSION_BUS_ADDRESS in the same way it forwards DISPLAY. However
I don't know of any efforts to patch ssh for that.
