If all initial contact goes through a rendezvous point in the data plane, then you can reveal a location at any time, based on information you gather (you don't have to guess what their intent is, like you do with caller ID on your phone). Also you can reveal different locations to different callers using higher layer protocols, for example SIP redirect once you complete setup, but redirecting different people in different directions -- revealing what you wish.

My point is that "cloaking" should not be engineered as a rare, inefficient attachment to the Internet protocol system. It's going to end up being the majority case. There will always be a way for people to advertise everything about themselves by short-cutting that. > Cheers, > > Ran > > We're in the Netherlands, make sure you pronounce that right :-) Scott
