15:01 < tonyg> samth: even tcp has this automatic-resource-allocation thing 
               that we described yesterday for rudybot-big-bang! to open a 
               connection, advertise (you your-port target-ip target-port) and 
               subscribe (target-ip target-port you your-port)
15:01 < tonyg> and to listen, advertise (you your-port * *) and subscribe (* * 
               you your-port)
15:02 < tonyg> note that where the wildcards are permitted varies between the 
               languages used for ad patterns and sub patterns!
15:02 < tonyg> (uh, and the driver uses presence/directory to auto-open and 
               -close the underlying sockets)
15:35 < tonyg> Oh UDP has the same pattern (though less restrictive)
