Why wouldn't periodic polling with GetMultipleResourceProperties work
for this case? 

Would a change incur notifications or is it simply time-based?

Subject: [wsdm] Asynch data collection

In thinking about the discussions last week in terms of getting change
events and Heather's use case, it occured to me that perhaps we were
missing a key capability.  Consider the following, I simply want the
management provider to periodically send me the current values of
properties (including metrics).  Rather than trying to register to state
change events, which has both problems we discussed, the complexity of
the registrations and the
potential quantity of change events for highly volatile properties.
Also,
since WS-N does not have the granularity to subscribe at the level we
discussed (deltas, percentage, etc). 

If we had a capability that allows a "manager" to register for periodic
posting of properties, optionally with a list of properties of interest.
In
some regards, this is very similar to the model used for events.   In
fact,
I believe it could be thought of a capability that changes the
publications of a management provide.  These could be annotated as
'registered" property change events. This has the side effect that one
manager could register and other could potentially subscribe to the
data. 

Thoughts?
