That is exactly what I wanted, thank you very much!

That is similar to another idea I was thinking of. Basically, if using
selections is not possible due to the clone area needing to be the
same size/ratio of the target display device, I was planning on having
either a tray icon or a panel applet that would function as follows:

click the applet/icon, a list decends. In the list is each available
output device. Moving the mouse over one of the output devices
provides options to manipulate that device. Options could be:
 -disable device / enable device
 -change resolution (further sub-menu? opens a dialog?)
 -clone area

if clone area was selected, a box the size of the current resolution
of the device would appear on the screen. The user could drag the box
to the desired location and click to clone that area. Maybe at that
point, we could use the compositing tricks you mentioned (if
compositing is available) to ensure that only the content of the
window that was present in the selection is outputted. On the other
hand, that could be quite annoying. There would be many cases, like if
you were giving a presentation, where you might want to drag something
into the cloned area so it is visible to the audience...

Thanks for the ideas and tips guys!
