does the rendezvous location really have to be the "original topological location" of the host or is that just how folks started thinking about it? and given that the rendezvous location has to be somewhere in the network, how can we get around the problem that that location might become unreachable no matter where it's located? I mean, you could replicate the information to multiple sites and use anycast to find a location, but would this fundamentally change the mobile IP protocol? Keith
