Google Desktop's blog mentions PlayStation 3 as an example of UPnP-enabled device. Google Media Server's team says that "the only way to connect the XBox 360 to a UPnP server, was to have a service that is only found on Microsoft services (used for registering for DRM content) and for the server itself to be claimed to be made by Microsoft. Legal would not allow us to pretend to be Microsoft (although there are other servers out there that do)."
