New SPKI-based network protocol

Dear all!

I'm glad to announce a new conditional access system network protocol
totally based on SPKI bare-bones certificates has been developed. This
network protocol has been designed and successfully developed in the
framework of the European Commission ACTS project OKAPI.

As major features we can list:
All network interchanges are represented as canonical s-expressions.
Provides privacy, integrity and authentication over all the actors.
Based on the Service provider - User scenario.
Network and application independent.
Suitable for data broadcasting.
Uses and exploits security features of public-key smart cards.

A kernel with an standard "C" API has been developed and will be
publicly available soon.

Comments, suggestions and questions are welcomed.
