__Do we want each registry to contain all the entries of all the others?__

How does a registry get hold of the contents of all the others so that it can answer user queries without having to query every other registry? Does it simply store the ResourceIdentifier for each resource in other registries, using the RegistryLocation to query the other registry if its user wants further information?

Do we want agents constantly getting updated information? Should a registry specify a set time during which it is willing to accept queries about how much data has been updated over a given period? Or should it treat the query asynchronously, dumping the results in some place where the querying registry can pick them up?
