That works great, just make sure no one's hooked up over a 56k modem!  ;-)
Man, this reminds me of a time when I was working at Environment Canada writing some scientific analysis software on HP Unix systems.  My buddy who was in an another room thought it would be funny if he pasted a few pix on my screen.  So I'm working away and all of a sudden some hard core beastiality pops up on my screen!  And then a few more pix!  Of course I'm frantically trying to close all the windows because I'm working in a public area, more like a hall way.  I just managed to close all the windows before my manager walked by!  That was close!  That was the day I learned how to set permissions on the display!  ;-)
