I actually did a little bit of work in 2003 along these lines -- a  
triple store behind a Cocoa Distributed Object, so it's basically the  
Mac Address Book but for RDF (persistent, system-wide, etc.)

The difficulty in demonstrating it was writing enough applications to  
demonstrate the interoperability benefits. It's certainly possible,  
though.
