I'm working on the implementation of an open whiteboard protocol under XMPP for a webclient, something I've seen asked many times before (JS whiteboard implementation). Since I would like this to be as standard as possible for comunication among all XMPP whiteboarding clients, I would like to know were could I have documentation of how coccinella sends whiteboard data, since (as far as I know) this is the only true whiteboard client until now.
Ideal would be to use an SVG comunication under XMPP, since this would make really easier implementation on webclients, and is a current standard. But I understand that you are just working on something alike, and I don't know how coccinella currently manage it's whiteboard.
I'll be waiting for your response.
