This is pretty interesting and might fall under a broader permissions and
expectations system.

I am going to send an email later to the list, but on the point of
suggestions I have implemented the first pass at a registry system for
webintents http://reqistry.webintents.org, which when you now use the
picker will show you a suggested list of services.  We need to work out if
a global system of suggested services is a good enough replacement for an
API or some declarative expectations system.

Try http://www.imagemator.com and you should see the suggestions in the
picker.
