Push and pull network filesystems with ccgfs http://www.linux.com/feature/148937 CC Network Filesystem (ccgfs) A transport-agnostic filesystem ccgfs is a transport-agnostic filesystem; transport is arranged by helper programs, such as ssh. Common transport modes are "pull" and "push", the latter of which makes it possible to export a filesystem located in a LAN to a DMZ host without defeating the DMZ security model which prohibits connections to the LAN, which the pull model would require.
