Couldn't this high level API be the API that David is proposing? Or
are these threads calling for something even higher level?

The API David is proposing is looking generic enough to me that it
should be no problem implementing in libraries other than NSS. Do you
see any reason it wouldn't be?
As a separate question, is anyone here familiar enough with keygen to
know if the proposed API could replace keygen?
