I think the XDCC Whiteboard feature in clients such as Visual IRC is quite compelling and would be a good feature to implement - not certain how much work it would entail, but it is something that I think would enhance the chat experience for a lot of people and may be something to help make IRC even better than it already is.

There is a scripted version available but I wouldn't mind seeing it added.

I would love to see DCC expanded in many ways, whiteboard, voice chat, video chat, etc. But apparently a lot of people here disagree...
