I didn't want to do an end run on Tim since he is one of the two authors
(Lange isn't the other) and he contacted me directly about the source
being available. But Lange should probably be involved. As you say, she
and DJB are normally doing stuff that are explicitly public domain. The
SW implementation of Curve25519 in NaCl for example.

Yes, that is what we want to do. My comment was just an observation that
nothing like that is included. In fact not a single test vector fo the
complete core. Unless I'm missing something, of course.

We would at least also need to add a wrapper to make the core interface
easier to integrate. No biggie though.
