Re: "cooperative" services (was Re: [DotGNU]Last call for 'This Year ...')

right. so there is a demuxer for connections, ie it uses one port say 
for the Jabber transport, but multiple webservices can use that one 
transport. so is there anything special about this type of cooperation 
verses a "normal" scheme where each webservice uses its own port and 
communication between webservices on the same machine would take place 
over the loopback? (if the answer is no, then that's good. otherwise, 
please explain)
