	I dunno, I haven't looked at user switching lately. davidz might
know ...

	I'm guessing user bar gets a new Xserver, and the screensaver runs on
user foo's Xserver ... so someone connected to user foo's session over
vino might see the screensaver.

	Not really sure, since the screensaver probably locks the display, you
might just see the last thing on the screen before the screensaver ran.
But then again, AFAIR Vino makes itself impervious to X display locking,
so you might see the screensaver. Or maybe not.

	You could install test2 and give it a poke ...

	Oh ... :-)
