Yeah, there's a bit more we're probably going to need too beyond just 
the info provided by libxenstat.  We'll have to identify those things 
and then (perhaps using libxenstat as a base) build an API (assuming we 
can't get the store to contain that function by then).

It would be very nice to have a centralized namespace to collect all 
xen-related information.  We'll have to think about how best do this.  
It seems a bit too ambitious for 3.0 although reasonable for 3.1.  It'll 
probably make sense to backport the 3.1 tools to 3.0 too as some point.
We'll certainly have to come up with an interim solution for CIM.
