    NFS ?

    The problem with OpenGFS is that it is a network file system so
    implementing "perfect" shared mmap semantics might actually reduce it
    from handy to useless. Right now the worst we have to do is mark pages
    uncached in some weird shared map cases, with pages being bounced across
    firewire its a bit different.
