RE: Top cloud in triangle/rectangle diagram

Ah, now I see how my name got associated with this.

In fact -- yes, I strongly agree that the scenario that David describes in
http://lists.w3.org/Archives/Public/www-ws-arch/2002Oct/0072.html is likely
to be a VERY common, or even dominant one for businesses like us.  We tend
to know our business partners and deal directly with them, but
standardization of that interaction would be very helpful.  Discovery is not
an issue that keeps us awake at night very often, at least when one is
talking B2B interactions.  Now inside our intranet there might be a
different story.

Yes, I see what you mean.  You could describe it that way, but that's still 
assuming that the role of "Advertiser" is required as a significant 
architectural component.  It could be for a particular EXTENDED 
architecture, but I don't think it's needed or desirable for our BASIC 
architecture.  I think the scenario described in 
http://lists.w3.org/Archives/Public/www-ws-arch/2002Oct/0072.html helps 
make this clearer.  (That scenario was actually inspired by the business 
need that Roger Cutler described at our last F2F, incidentally.)
