This is a very interesting development, there was an article here a while ago about multiple cursors & keyboards in use on a single display using a hacked X server.

There's also the MPX project from the University of South Australia: http://en.wikipedia.org/wiki/Multi-Pointer_X

on thing that wasn't mentioned was using higher level information to infer cursor position. ie: instead of just saying text disappeared here, text appeared here, say a cut operation was performed here and a paste operation was performed here.

This is a difficult problem to deal with, due to the nature of HTML and XML. They both use embedded markup instead of annotations so when you're operating on things, you're not actually operating on text, you're operating on a tree.
