Well, this doesn't seem clearly that different from the URN proposals
that the IETF has been kicking around for years. And from the Product
Description document, it seems as if it's at the same level of
granularity as any other "file naming" system. Nowehere near granular
enough for our purposes (at least at first flush).
Moreover, it sounds like their system is quite analogous to Gnutella
and the Ocean Store as far as object replication and distribution and
that's a huge can of worms to open when the data objects are not
themselves relatively static. I think its an important (eventual)
twist, but definitely not something we want to worry about at the
moment.
