Mark, 

Would you agree that there still is a discovery step done by a logically
separate party (i.e. not a servce and not a client)? May be not the
registry, but something anyways... I'm not talking about physical
implementation, but rather about the logical architectural components.
So if you were to draw that logical architecture would you include
Discovery Mechanism component then?

I agree, though, that it is definitely possible to implement discovery
without a registry.

Ugo,

Maybe so, but it still suggests the three-party model; A wants to
communicate with B, but is required to go to C in order to get the
necessary information to do so.

We know how to enable communication without a registry.  It's not
difficult.  Let's promote that.

Thanks.
