Presentation API and non-screen devices

Hi again,

Several people I talked to raised the fact that the Presentation API 
could easily address devices without "screen". A similar comment came up 
during the Advisory Committee review.

The fact is that the notion of screen is not a precise one. In the 2UA 
case, nothing really mandates the presence of a real screen attached to 
the second user agent. This is even more the case for 
application-specific content (provided the controlling browser supports 
it), where the second device may not support HTML. To that extent, the 
Presentation API already supports devices without screens.

The group has been focusing on scenarios that involve screens and I 
think that it is a Good Thing. Extending the scope to cover other types 
of devices could introduce additional requirements that could be hard to 
address, at least in this iteration of the spec (e.g. the possible need 
to specify the "type" of device being targeted). So I would rather stick 
to "screens" to start with. If successful, the working group could 
always re-charter to extend its scope.

I'd like to get your views on the topic though. Is this the general 
feeling or do you have other views?

Thanks,
Francois.
