JC, all
as I understand it, Web Intents is just a framework that allow application  
to "discover" other application via the mediation of the UA.
Even though some "discovery" mechanisms are part of the spec itself (e.g.  
the mark-up elements) I don't think that is intended to be the only way.  
Furthermore, even if intents provide a way to discover a service, we also  
need to address the communication part to fully cover the requirements  
around communication with home network services. This last part needs to  
be done somewhere else (in DAP).
