On the mac, the accessibility framework is more restrictive -- its up to
the application to conform to Apple's specifications. I don't think
that changing the shape of the cursor would do the trick, the
accessibility framework needs to be informed about everything, when the
cursor moves and many other things, the details of which I do not know,
but as an example, Microsoft Word is complete inaccessible on the mac,
Microsoft won't conform and Apple says heck with you -- in other words.
