Thanks for that sentence, now I think I got it: Web Intents does not provide a discovery mechanism. Web Intents provides a registry and broker mechanism. So if another technology provides a discovery mechanism (e.g. the UPnP service broadcast announcement, SSDP) and some entity implements the adaptation from SSDP to intent registration, the Web Intents can be used as the interface from web apps to services discovered with the other technology. All my confusion (shared by others I believe) came from trying to understand how Web Intents provided discovery, which was hopeless :) We just need to make sure, by implementing it, that it is possible for some entity to implement the adaptation from SSDP to intent registration.
