But the question we are asking ourselves is: is it possible to cover this

The goal is either to see if there are suitable open standards to reuse or  
if we need to define something new, as needed.

And even though there are some existing standards we may want to support  
(e.g. UPnP) we should not restrict ourselves to this since there could be  
several reasons (technical, commercial etc) why one would want to  
implement the same use case using a different underlying technology. The  
question for the future WG would then be: can this be achieved with a  
common approach? This is up for discussion, and we had already a first  
brainstorming as captured by Clarke in ISSUE-9

That is why I think, once again, we should keep our usecases generic  
Mentioning UPnP, Bonjour, Bluetooth etc is fine IFF 1)there is a  
justification for it (X% devices on the market already support this) 2)we  
don't restrict ourselves to that.

This taskforce is not a UPnP TF, so we are not doing a gap analysis of
