The unique IDs will someday be used as part of the NodeRevision primary
key -- that's necessary to support distributed repositories. Instead of
using a GUID explicitly, Bill suggests we hava (repository-specific)
mapping between GUIDs and RepositoryIDs. The RepositoryID namespace
would obviously be more compact, and therefore kinder to database
indexing routines. I suggested that the repo's own GUID would by
definition map to a Repository ID of 0.
