CXFS runs on Linux, Windows 2K/XP/2003, Mac, Solars etc.

On Windows you are presented with multiple filesystems under a single
drive letter. What filesystems are mounted on the node are managed
centrally, once each Windows box is configured with CXFS no further
CXFS administration is needed on those boxes. When a Windows box is
rebooted it automatically remounts all the CXFS filesystems.
