FWICT: Streamlined NTRU Prime (sntrup) has no known patent issues.

Should be fine.

Regardless, a "double-wrapped bitcoin address of some kind" can be
specified, coded up and the relevant module replaced whenever the dust
settles.

I know Bitcoin doesn't (yet) have fee "weights", but i still think these
addresses should be called "heavier" if they are at al significantly slower
to validate.
