Check out https://github.com/stephenmcd/drawnby - I built it for the 2011 
Django Dash (and got 3rd place!). It lets users draw to a canvas element in 
the browser, and pushes the changes in real-time over web sockets, so 
multiple users can collaborate on the same image at the same time. It then 
stores and displays the results as PNG images.

I can't offer any support sorry, but hopefully having the source might help 
you out.
