Hi Richard,

Actually the verisign declarations for this seem novel
to me. Maybe no worse that the MAD ones you referenced
but I do think there's novelty there, so people who
care may want to (get someone to) take a look.

That said, encumbered crypto tends to not prosper unless
there is no alternative, no matter what licenses are granted,
and it's not clear to me this case will differ.

I guess I'll think about it if/when the RG chairs issue a
call for adoption.

Cheers,
S.
