Thought about this using Intermezzo - basically the same idea.   I think the
problem is that these are on-demand replication mechanisms that get the file
when they need it instead of push-to-other-node-on-write sort of deals. I'm
not posive about that.  The other problem is how these filesystems handle
changes to large files (like FileStorage). 

There, might, in theory, be a way to integrate this with something like
DirectoryStorage, but I think you would need to do some heavy scripting to
get things to work just right (perhaps to the point that you might as well
manually set up scripts to low-tech replicate files?).

On a related note...
thinking of using coda (http://www.coda.cs.cmu.edu/)
to address the single point of failure for our
zeo storage. But I've never used coda. Anybody done it with zope?
Issues?
