That's what I thought, but I'm thinking this won't quite work for this  
case.  Our agent is actually an HTTP server, and we hand out URLs to  
stuff it serves up, e.g. http://localhost:12345/foo.  If we use a  
dynamic port, even with Bonjour, our URLs are no longer valid.  Unless  
there's a way to specify Bonjour ports in URLs?  I thought that only  
worked for host names, though (i.e. <name>.local).
