Filesystem Journaling Update II - July 2005

    Sure.  All the userland programs could trivially be ported.  It's the
    kernel side that would be difficult.

    And, yes, the idea here is to use the journaling to mirror off-machine,
    to a 'backup' box on the LAN and from there completely off-site to 
    backup boxes out on the internet... and for all of that to work in a 
    robust fashion.
