i know this doesn't answer your question, but what tablet do you use to write equations? i tried writing equations on mine but it looked like drunk spider caught in a fishing net.
Does anyone know of any math chat rooms where people use headsets?
This forum and also tutor.com have helped me a lot but using voice chat would quicken a lot of things. Ideally, I would like a place that also uses shareable whiteboards. With my tabletpc it's a lot quicker to write my equations than to use latex.
P.S. If noone knows of such a thing, contact me if you're interested in starting one up.
This is a little late. But while I was a graduate student at the University of Iowa we built a site just for this purpose. Two years later we have a large community, video conferencing, whiteboard, file sharing, Latex editing, and more. Please check it out. Home - Tutor Universe
