Hi Willi,
If one looks generally at the two architectures (MIP, HIP), one can see 
many similarities in the approaches, from different starting points and 
emphases.  MIP was originally oriented towards home-agent tunneling, 
while HIP was originally oriented more towards end-to-end handling of 
mobility.  But MIP was later extended for route optimization, and HIP 
was later extended with home-agent-like functionality (HIP rendezvous 
servers, HIP relays).

I was not advocating for HIP here, merely trying to clarify and summarize.
