I disagree with much of it. For example: "With Web Services, if you can read SOAP you can write SOAP. If you can write SOAP you can read SOAP. So modulo only the firewall issue, everybody's a peer." I don't understand that statement at all. If you think of "the firewall issue" as the issue of: * how do we address nodes (IP has limitations here!) * do organizations want end-user nodes to have addresses? * how do organizations handle security policies for incoming messages? * are organization's goals aligned with end-user's goals Then he's saying: "Given that a Mexican made the trip from Mexico city to Tijuana, immigrating is just a matter of crossing the border and presenting oneself at the INS office." Clay knows, as well as anybody, that the problems in P2P are really, really hard. And he should know, as a programmer that reading/writing messages (whether SOAP or HTTP) is the tiniest, most insignificant part of the problem. So I really don't understand that bit at all. I also don't see *any evidence* in the SOAP specification that it is more adept at bidirectionality than HTTP. After all, the part of SOAP that works interoperably uses HTTP as its addressing and transport mechanism so if you can send a message to a SOAP peer then you can send one to an HTTP peer. In theory, SOAP could run on a P2P system like Jabber but what's the point? If Jabber has already solved the hard P2P problems then what is SOAP adding other than buzzword compliance? Paul Prescod
