Since one of the cardinal "Is it a grid?" tests is non-centralized
control, the full registries would have to be mirrored.  Any institution
taking on the responsbility for a mirrored full registry would need to
ensure they have the people, funds, storage space, and security against
illegitimate registry entries.  A network of limited registries sounds
less scary for upkeep, but, as Tony said, the full registries would reduce
the complexity of "all" type queries.  (I hope I didn't just repeat what's
already been said.)
