I haven't studies this RFC carefully, but it looks to me like
the rendezvous service is potentially distributed, but in
the sense that everyone can pick their own rendezvous server,
not in the sense that the rendezvous service is collectively
provided. This means that I need a real relationship with
my RVS (in a similar way that I might have one with my
SIP registrar). I need to know that it will be online whenever
I am or I will be unreachable.

The whole point of a distributed rendezvous service like that
provided by P2PSIP is that the various members of the overlay
collectively provide that service and as long as one of them
is up, the system works, thus removing the need for an explicit
service relationship with some server.
