    I wish it would. Most of the research and stuff so far has either put
    the file system into the disk firmware (upgrade hell). Having a disk
    which talked entirely about

    read(handle,offset, length)
    write(handle, offset, length)
    alloc(handle, near_handle, length, otherhints...)

    might well work out rather better. It also allows the disk to do fairly
    major relayout of data as it learns usage.
