Cell phones make the solution attractive, and the solution is most needed by cell phone users. You need someone's phone number (and Mobile IPv6 home address). You get all you need from the target phone *when needed*, if authorized by the target user. Or, when you meet someone and want get your phones paired, you just type the target name because you have your cell phone in your hand. The phones get paired. You don't need to type a long SIP URI and Mobile IPv6 home address. as the > information sought could easily be any sort of communications > establishment information.

I'm not sure what you mean by large scale. I suspect that it is an unnecessarily ambitious requirement. A local solution is already very much needed IMHO. If you really want to build it, I suggest you uncouple it from SIP, I don't know about solution space, currently. Discussion needed to start somewhere, SIP WG was an obvious place.
