I have now updated the language so that it is clear that we are no trying to get into a debate about keychain protocols. Rather the notion of a KeyChain is added to help make certain distinctions that make certain questions disappear. It also is a lot closer to how software actually works.

A Key Chain agent can return certificates to authorized <tref>Clients</tref> and can sign cryptographic tokens with the corresponding key. This protocol does not specify where that agent is: it could be that the <tref>Client</tref> contains his own Key Chain or it could be that the Key Chain is a seperate process on the Operating System.

When someone looks at my client (IE) they will find no key chain, and no "key chain agent" and no protocol between the IE ssl client (a library called sspiclient) and said agent. My code now looks like its missing elements (i..e is incomplete).

I can also note the shift in technical language use in the last 3 weeks. Its better, and much tighter. The reviewers are doing a good job. The language shift also gives hints about the new mindset.
