I was thinking about someone (I cant code:) will write a program like an on-line classroom. perhaps using the NX protocols or whatever.
the basic thought for it is to if if someone has a problem, say, with math homework, he could use exciting tools to draw/type it quickly, and we could share a drawingboard in realtime.
audio and video support would be nice too, i think.
hope somebody likes the idea and make something of it.
feel free to contact me perhaps for more details/thoughts about the idea.
