One could argue about adding 128-bit Twofish as well/instead,
as it's been around longer and also went through the deep AES
process scrutiny.  However, on Camellia's side, it is a post-AES
cipher, and so benefits from more recent insights / design
trade-offs, PLUS it has gone through the scrutiny of both
NESSIE and CRYPTREC.  In addition it's already implemented
(in both 128-bit and 256-bit lengths) in applications (e.g. the
Linux kernel and Firefox 3.0 [beta]).

I have no objection against your opinion that about Camellia.  It is
well designed cipher.  I mentioned that most important thing is that we
need 256-bit for some security reason for OpenPGP.

One outstanding question I see: have we ever had a reply back
from NTT giving an IPR statement SPECIFICALLY for OpenPGP, as
requested by Hironobu SUZUKI here?

Yes.  I already have discussed about it with a NTT person who is a team
leader of Camellia project. They will give an IPR for OpenPGP.
