Input Tablet to Webpage Chatroom

[jrsjrs]

I have been looking for a solution to this problem for a long time.
Any guidance from anyone would be much appreciated.

I have a website with a chatroom. I wish to add "tablet and stylus" input to this chatroom because most of the questions need technical-type diagrams to answer them properly.

In other words, I would like to answer the questions by writing them onto an input tablet of some kind with a stylus, and have my explanations appear immediately or in real-time in a window of some sort in the chatroom of my webpage.

Windows Messenger is not appropriate because it gives someone unknown to me access to my computer.
The only other option is to upload it after I have drawn it on my own screen, which would be much too slow.
Using a webcam might be a solution, except that there is that appearing-hand annoyance, and when a webcam is already being used to show the presenter we then require a second webcam.

Any thoughts? Is there any company out there that makes such a product?

Have you looked at any of the groupware available on Sourceforge.net? Most of that is free, and provided with source, so if you find something with that capability, you can probably find the code for it as well.
