    Hi,

       I've noticed that the driver I am basing my M3091 work on, the
    M3096 driver which was in turn derived from the Coolscan driver, uses
    a separate process for reading data from the scanner, which is then
    fed via a pipe file descriptor to sane_read.

    Other drivers (like the Bell+Howell backend I've been looking at for
    duplex inspiration) don't use a separate process.

    Which would be the preferred way to implement it for a max. 15ppm ADF
    scanner?

    Bye
    Frederik
