Also, I'm not sure how ccd and nfs interact, but given that ccd isn't
meant for data security (use RAIDframe) and nfs has many interesting
issues, I'm not certain I would trust my data to that.

I *believe* that, presuming the NFS server itself will not fail and
such, that RAIDframe over NFS *may* work. I'm no developer or even too
good at filesystems, though, and I would recommend a lot of testing.
