True, I was more thinking of their motivation towards others.

Good points on Ed25519. Hopefully IETF decides on that in the end. And
some of the stronger Ed-curves too.

For Cryptech, the use cases we have that use 25519-something all use
Curve25519 I think. And they are really not the same curves and we
therefore need support for Curve25519 first. Unless I misunderstand
something here. I'm slowly learning and doing test implementation of
curves to get a feeling for what kind of beasts they are. Right now
mostly related to P-256.
