I need to set up a network fs, so that I can mount a directory from Box A on to Box B and Box C. However, I need those files to not be transferred from Box A upon every access request; basically, I need the files cached locally, and only updated when pushed from Box A.Any suggestions?
Network Filesystem + Local Access

You might benefit from using NFS and CacheFS.  It should be available on most modern Linux distros.
