"Typical" use.

If I understand you correctly though, you're concerned that a single GET
may result in more than one "response".  This presumes that a single
event notification is a single response.  I believe it's perfectly
reasonable and consistent with the architecture of the Web to define a
resource whose state is not expressible in a fixed size representation. 
That's what they're doing.

This isn't to say that there isn't a better way of dealing with this,
specifically the interaction with caching proxies, as it may still be of
value to cache individual event notifications.  I'm sure they'd welcome
your input on that topic (and I wouldn't mind hearing it too 8-).  Drop
