> Aren't Microsoft already "standardizing" this with their Universal Plug and > Play (UPnP) architecture? That's just midcom, which the IETF is standardizing. We started before they did but Microsoft got there first and worst (there's even midcom language in their documents). So that's something that was started in the IETF and expropriated. Note that it still handles incoming connections pretty badly. There are other IETF efforts, as well, which I think are more sound, but may take some time to become fully ramped up. Melinda
