Getting off-topic but I'd also like to hear who uses a parallel
distributed FS, and what problem space they work well in.

GFS works fine, but we have trouble scaling it up due solely to the
limits of central storage.  I'm sure there are esoteric storage designs
to get around this, but at some point I also suspect there's an easier
way...
