Along the same line but perhaps more interesting than 'reconnectable' X
would be 'reroutable' X, where you could redirect output from a local
display to a projector (Star Trek: "On ViewScreen!"). This can be done
with proxies or double-rendering, but it would be interesting to try it
at the toolkit level.
