True, but you could implement the same behavior as Java Applets (the 
border of the screen pulses slowly and a warning icon shows up when the 
mouse approaches it. When you hover over the warning icon a tooltip 
shows up reminding you that you're running inside of an applet). We 
could do the same to warn the user that the contents of the box is being 
shared. This is actually beneficial from a UI point of view, because you 
won't necessarily be sharing the entire screen.
