I need to tutor my brother on a particular topic. We live in different geographical areas. We use g-talk to do the same. We do not have web-cam's to enable video chat.
The tutoring will involve a lot of off-the-cuff illustrations. I am hence searching for a suitable software which will emulate a blackboard over an internet connection. I need the software to enable sharing of a common canvas on which I can draw, write and point to. Say a Microsoft paint canvas on internet.
Could you point out a suitable software? Google is not of being help at the moment as I suspect that I am not specifying my search criteria properly.
