    I'm going to bump this topic a bit, since it's been a while..
    There are still some issues with ide-cd's SG_IO, listed from
    most important as percieved by me to least:

     * Read-only access grants you the ability to write/blank media in the drive
     * (with above) You can open the device only in read-only mode.
     * You can't open the device unless there is media in the drive
     * Still seems to be no way to specify scatter gather/dma buffers yourself,
       though I'm not entirely sure that matters anyway.

    The read-only granting write/blank seems like a pretty serious security issue
    to me. Not being able to open the device without media is merely extremely
    annoying (and I suspect fixing it would break a lot of programs).
