I’ve been reading a little bit about UPnP (Universal Plug and Play), after getting a few Linksys routers that support it, and I’ve gotta say that it sounds like a cool technology. Unfortunately, there don’t seem to be that many devices that use it yet, and more, there don’t seem to be many places on the web to read about it. The two best ones that I found are the resource page of the official UPnP standards body (which tends to the technical), and Microsoft’s overview of UPnP in Windows XP (which tends to the practical).

Update: Microsoft is already using UPnP in useful ways; for example, the Remote Assistance feature automatically senses if it’s behind a UPnP-compliant device, and translates the computer addresses accordingly.
