Universal Plug and Play, an Intel-centric norm that is used for things like dynamical location and configuration of network devices (it is quite different from Rendezvous in the sense that it covers both service discovery and interaction).
It can used for remote control of Windows Internet Sharing, punching holes in UPNP-enabled firewalls (MSN and most Bittorrent clients use it for precisely that purpose), etc., but most recently for configuration and media sharing among entertainment devices under DLNA.
Of course, Apple seem to keep wanting to do their own thing, and their own thing only, so there is no native UPnP support in Mac OS X – nor is it likely to ever happen, thanks to AirPlay and the like.
