(I assume you are talking about an xterm whose DISPLAY is 'foo:0'.) The difference is that if you run bar on foo:0 from an xterm on foo:0, bar will probably have D-Bus environment variables for foo:0 in its environment, whereas if you run bar on foo:0 from an xterm on baz:0, bar may have D-Bus environment variables for baz:0 in its environment. (At the moment, I think ssh does not forward D-Bus environment junk, but that 'feature' could be added fairly easily.) The protocol they were discussing would have had bar display its own UI using $DISPLAY and send a startup notification using the D-Bus connection specified in its environment. Robert Ransom
