[Bioclusters] Need NFS with local disk based caching, CODA?

[Timothy E. Miller]

If you like NFS and want local caching, you are almost 
describing AFS.  Look into OpenAFS at www.openafs.org.

It authenticates via Kerberos but you can define your
directories to be read/write by unauthenticated users.

I'm not using it on my cluster (setting up GPFS describe
by someone else as we speak) but I use it (client side)
for research related software distribution.
