How about the reverse ? By default, clamp the cursor in the visible
regions, and when the "mouse" tries to go past a border, fire an event
and ask (the WM or anyone) what to do (i.e. go to another island, or do
a nice 3D cube move, or start panning, or start "exposé" ...).

Maybe if there's no one listening to the events have a set of default
workable policies, to be able to move the focus to an xterm when the WM
has died, or is border-event-unaware.
