Graffiti is a whiteboard (for Linux, Mac OSX, Windows etc.) with networking capabilities and has a XML based independent protocol and can be implemented in various other protocols like Bonjour and Jabber. It offers a collaborative space where you can discuss your ideas, share photos and files, discuss presentations or just draw together with peers for fun and whatnot.

It is supposed to be integrated in some open source projects: KDE(as part of KDE apps Kopete, Kontact etc.), RetroMessenger and IceCuBe Messenger. The architecture is made so as to provide a standard xml based whiteboard which can be used in any open source project.

Graffiti Features:
1. Raster(Bitmap) based drawing capabilities
2. Tools(pencil, eraser, color picker, clear all, text, line, rectangle, ellipse)
3. Image previewer
4. Network Chatting
5. An automatic peer detection mechanism(kind of ZeroConf) over LAN using UDP broadcasting.
