This entirely misses the fact that zfs (open zfs/zfsonlinux) is open and cross platform.

Which is almost more interesting than all the good stuff that comes with zfs (volume management, disk management, software raid-like functionality, encryption, snapshots, send/receive).

Its the first time we truly have a half-modern filesystem with safe write support and sane performance across many different os's. Even if just made dual booting freebsd and Linux this would be a fmgreat win imnho.

If the choice is between zfs and fat32...
