They'll be liked ManagedProperties, but you don't need all the support for changing
them :-)

e.g. psuedo code:

  | public interface ManagedObject
  | {
  |    // ...
  | 
  |    Map<ServerName, List<MetaValue>> getStatistics();
  | }
  | 

What is required is a way to refresh (re-retreive them from the server -
perhaps individually) and also being able to understand that the statistics are 
available multiple times from the different servers in the cluster where the object is deployed.

Where they do look more like ManagedProperties is the ability to annotate
parts of them to explain how they should be used, e.g.
whether the statistic (or a component of the statistic)
is monotonic (always increasing) or random
or whether the it is an average, etc.
