Subject: [Hipsec] HIP-based anycast

Hi,

opportunistic mode with the help of a rendezvous server could be used 
for implementing HIP-based anycast. The current RVS specification does 
not allow this:

http://tools.ietf.org/html/draft-ietf-hip-rfc5204-bis-02

4.3.1. Processing Outgoing I1 Packets

    An initiator SHOULD NOT send an opportunistic I1 with a NULL
    destination HIT to an IP address that is known to be a rendezvous
    server address, unless it wants to establish a HIP association with
    the rendezvous server itself and does not know its HIT.

I think we could specify either a flag in the base exchange or 
alternatively a special HIT encoding for the "NULL" destination HIT in 
the I1. What do you think?
