Not sure of this, but wouldn't it risk clogging down the chat traffic if a (big?) number of people are feeding in live webcam images? Moving image feeds take much more bandwidth than sending text msgs, so it might cintribute to having the chat engine stocked, and with the tech problems we've had for some time it could be too heavy.

Other than that I'm kind of intrigued; I agree it's a good idea though as for myself I'd always want to control *who* was watching me.
