I think Ard’s point is valid: in the long run we don’t want two competing software implementations of each primitive. It clearly *should* be possible to make crypto API call into zinc for synchronous software operations, but a demonstration of how this actually works and that there isn’t some change to zinc to make it would well would be in order, I think.

IMO the right approach is do one conversion right away and save the rest for later.
