RE: [Int-area] Progress on draft-laganier-ipv6-khi-01.txt

I think for this experiment a longer prefix is fine,
even /40 or /48 unless there's some strong reason it needs
to be shorter during the experiment.

Personally, I'd eventually like to see something like a /8
followed by an org id (like ULAs have).  Since ULAs have 32
bits for such an id, that's how I get /40 (or /48 if eventually
there were a /16 like ULAs use, followed by 32 bit org id).
This would solve some problems HIP doesn't solve today,
which were pointed out in the SHIM6 meeting in Dallas.
(e.g., PTR records for HITs aren't feasible today since
the reverse zone would be flat).

The use of a long prefix for the present experiment could
be consistent with such an eventuality in the sense that
the hash would be truncated to about the same number of bits 
(like 80 or 88).
