glad to hear that.

Agree :)

May I ask you to suggest some specific re-wording of the current  
requirement draft[1]?
Just to be sure your comment is correctly reflected and to let people  
react on what you propose
Feel free to post it here.

That was not the intention, but I agree that this is misleading.
We need to generalize it a little more and probably use a more "neutral"  

To be honest, the use of 2-box/3-box model terms was good at start to let  
people understand at a glance what we are talking about.
But I agree on a reworking of this part. As said above, if you have a  
proposal, feel free to share.

partially agree, in fact the current draft mention JS API only in few  
places, while it usually says "User agents should provide a means for ...".
We can generalize even more and remove any specific mention to JS API.

On the other hand we need to have this discussion at some point. Not only  
if we need an API but also which kind of granularity we need for these API.

maybe we should use the term "Service Discovery and Control"?
