I'd really love so see a trustworthy curve that has an extremely high security margin... something like "as long as there are no quantum computers and no other break through against the base paradigms is found - no collected computing power will 'ever' be able to break this"... that could be used in fields like OpenPGP... for long-term key signing, where performance doesn't matter that much. Cheers, Chris.
