Have you looked at NUFA? The latest NUFA and distribute translators
are compatible with each other. You can have the 'writers' in a NUFA
cluster (where they write to local nodes, but with a global namespace
-- everybodys data accessible). With the same volfile, you can replace
nufa with distribute, and have external machines access this volume as
well.
