Martin,

Thanks for the response!  I'm looking at those specs now, and I really like
the flow of the HTTP Authentication spec, because it looks like it's solving
the problem of passing the OpenID Identifier to the RP in an automated way,
which is really cool.  Looks like it needs to be "fleshed out" in some
parts, though.

As for the Signature Request protocol, I'm not quite sure what it does yet,
but I'll let you know my opinion once I've digested it.

Thanks!

John
