Complete re-write. Zot is now an extension of and encryption wrapper for salmon and provides a foundation for openid based access control for any web resource to any webfinger identity. It is designed to be upwardly compatible with both OStatus and Diaspora and represents a model for a web based messaging infrastructure which can ultimately bridge traditional email with web based social networks.
MIME messages and the bridging of SMTP with webfinger and social networks aren't completely specified in this first release but are noted as this is where the specification is headed. There are some details to work out on the necessary extensions to rfc822 and its derivatives (when used on the web) which require broad concensus.
