This is already a feature of Microsoft Exchange Server, where it's called Single Instance Message Storage (it's also a feature of umpteen other database-structured mail systems, including crufty old cc:Mail). It's possibly where "Bill Bolosky and two Microsoft colleagues" (who appear to have been thrown under the bus for old Bill, here, in the official credit-for-the-idea department) pulled the idea from. I wouldn't be surprised if we're giving them too much credit, though, by assuming that they haven't merely reinvented true sym/hardlinks for the Winblows 2000 family.
