Hi Mark,

I like the RESTified version - simple. 

From a WSDL point of view, that's just a binding. So whatever
the abstract syntax we agree on, we could define a RESTified 
HTTP binding using the MONITOR method as you did quite easily.
The discussion we're having now is above binding details - its
more about how to tell someone that a service has something
it can notify others about (i.e., an event it can generate).
Everything in your example fits nicely under the approach I
proposed - you have a notification service reference (the
reply to header) plus subscription data which seems to indicate
what info the subscriber is interested in.
