seems sensible.

it's doable.

we probably have geometry information kicking around somewhere at that point, 
but the other screen's geometry may now have changed as well.

figuring out "next" is not so trivial. which one is "next" if it's the middle 
of three screens? if they are stacked vertically? etc.. again, doable, but 
would take a bit of work.
