Maybe, but I don't. If we have a standardized version of that button, it will 
probably over HTTP. For that, we would need to have a discovery mechanism for 
"where is my parent's web site with the button", which is very hard. It is 
possible, and could even be signaled in the DNS with a URL RR (thank you 
Patrik!), but that will take a lot more discussion. I propose that if people 
want to do that, it be done as a update to this document.

The question is the same as above: notify whom?

To me, the polling option is well-described and the most likely one to be used 
because it takes so much less new stuff.
