It's short but we've discussed this together last week, and DAP intends (no pun, err, intended) to rely rather heavily on Intents so we'd rather move fast rather than wait for WebApps to recharter, which could take a few months.

Opera would like to explore Local Device and Local Network Discovery as 
a subset of Web Intents. At this point, having studied the Web Intents 
proposal, we're unclear how this would work considering that:

a.) to register a URL endpoint as an intent provider the user must visit 
a web page (presumably hosted by the target device itself) and capture 
the intent registration from that page before that intent provider can 
be used within the UA.
 >> WHAT WE ACTUALLY WANT: to enable auto-discovery and 
auto-registration of local device services and locally networked device 
services to the point that the user doesn't need to go out and register 
local devices and services upfront. When a user requests a particular 
service, they can then directly choose a device that implements the 
requested service rather than having to go through the indirection of 
searching out, navigating to and registering each intent provider first.

b.) to then subsequently use a registered intent provider the concept is 
to open that provider, again as a web page in a seperate tab within the 
UA. From here we can then establish a bi-directional web messaging 
channel on which we can send and receive messages to communicate to and 
from that web page that is representing the current local service.
 >> WHAT WE ACTUALLY WANT: to communicate transparently with a 
locally-connected service (after user authorization has been 
established), without requiring that service to manifest itself as a web 
page in a new browser tab. We'd also like to speak the protocol (web 
sockets, http, etc) that the device currently supports.

My assumptions on Web Intents above may be incorrect. I'd appreciate 
some clarification if this is the case.

Perhaps someone could take the time to describe exactly how a user could 
communicate with an existing TV device in their home from a web browser 
supporting web intents based on the above requirements?
