I've only started now to look at the proposal but let me start by  
clarifying one thing

To be clear: I'm not going to work on this action because so far is still  
not clear to me where we are heading.
Furthermore, if we were to design a solution for "legacy" devices that  
will by design work with any device,
so I'm still not sure why we want to keep the 2 separate.

Most of the discovery part needs to be done inside the UA. By defining a  
new service (VS mapping well-known intents on well-known services) you are  
adding burden to implementers that needs to support both.
By further extending UPnP and mDNS you are adding yet another burden.

What is the advantage in slightly changing existing protocols? And if you  
are extending them anyway (i.e. you cannot reuse existing  
devices/libraries as is) why not just picking one protocol?
