[foaf-protocols] webid-linked claim verification?

Well, actually, as a website owner, i don't want to be discerning
anything. All i really want to do is just send messages to my clients. I
want all that discerning to be out of my sight and concern and totally under
the client's control. That is my real point here. And, when you think
about it, if the libraries take the approach of factoring all that
discerning into the control of the client and just let the website send (and
perhaps recieve) messages from the client, then all that magic we want can
evolve in the libraries and my web development code can be left alone. Me
thinks this is a path to a faster evolution for all those wonderful WebID
benefits that are being touted.
