I have two computers one is a macbook pro and the other one is a windows xp and one is in one city and the other is in another city and I was wondering is and where can I get a softwear that lest you draw like a white board over wifi and then the other person on the other computer can draw on the same board and we can both see each others dorowings and edet them?

If two people in different cities using computers that run different operating systems want to collaborate on a drawing or collaborate on anything for that matter, they can use a virtual whiteboard.

Virtual Whiteboard is real. If you register and use it, you can use it all day. If you do not register, each session is limited to just 15 minutes.

Well theres not a program i know of, but what you can do is draw something on one computer and then email it to yourself or whoever you want to send the drawing to.
