Depends more on the quality of your PRNG.

Could be in OpenPGP later this year. Camellia was fairly fast.

As I recall, there is some coordination among the OpenPGP ECC author and the
maintainers of other FOSS crypto software so they implement things in a
compatible manner. I believe they may be waiting for a SHA-3 algorithm to be
picked. It was discussed on the IETF-OpenPGP list late last year.

"It certainly isn't in the commercial PGP." Not Yet, although as Rob said, I'd
be surprised if PGP (symantec) didn't already have an ECC-enabled branch waiting
to release once the ECC OpenPGP Draft is adopted. Two reasons:

  1) One of the main initiatives of Suite B is the use of COTS,
     and the USG represents a VERY large market for PGP.

  2) The ECC-OpenPGP draft itself. Andrey Jivsov, the author,
     is with Symantec Corp (read PGP Corp).
