Certainly.  My window manager wants to display one of nine different
cursors during a resize operation, depending on which ninth of the
window the mouse is in.  I create ten InputOnly windows, one of which
blankets the window to be resized, with the other nine tiling the big
one (the nine are children of the one).  Each of the nine has its
cursor set appropriately; I then grab the mouse with the one as the
confine-to window.  Then the server automatically handles restricting
the mouse to the area desired and changing the cursor to match which
ninth of the area it's in.

It might be possible to get the same effect with InputOutput windows
with backgrounds of None and border-widths of zero, but I'm not sure
the semantics would be quite right.
