well, the way i've split up the work is by defining a document for the
REST framework itself which makes defining profiles very easy, but
left monitoring out of it.

There is then a separate document for monitoring of the HTTP resources
- I've done some initial work [1] on a interface for monitoring HTTP
URI's over a SIP event package, although other protocols could also be
defined in the future (e.g XMPP, COMET, BOSH, AMQP).

The reason for working on a SIP event package for notifications was
that the use cases within bliss most commonly involve running on a SIP
UA - although by splitting it out of the main document others can be
added as there is the need.
