A collaborative "whiteboard" program I tend to find myself helping out my friend on his homework once in a while and i find that it would be sooooooooooo much better if i could actually show him hte work i'm doing and exactly what i'm talking about. Does anyone know of a virtual "whiteboard" program that I can run that he can connect to over the net? I've tried MSN messenger's whiteboard program but it never works! I and i and it never works! Also, what's a good tablet? Are they useful for handwriting on the computer? I have a sneaking suspicion that it does not transmit fast enough so that you're writing is real-time (as opposed to like a 1/2 second delay).
