About licensing out of your csp - did you check that you didn't violate any
of EC patents hold by Certicom? http://www.certicom.com/index.php they are
currently holding more than 300 patents with most of them related to every
aspect of Elliptic Curve Cryptography.
and if I remember it correctly - they also have commerical ecc csp...
(note - I'm not associated with certicom in anyway).
