ZFS-FUSE is horribly unstable, although that's more an indication of
the stability of the storage stack on Linux.  We've been testing it at
work to see how dedupe support will affect our FreeBSD+ZFS storage
servers.  We can't keep it (Linux+ZFS) running for more than a few
days.  Drives drop off at random, the pool locks up, resilvers never
complete.

When it does work, it works nicely.  It's just hard to keep it running.

You definitely want to do the ZFS bits from within FreeBSD.
