What I miss in previous arguments is what is wrong with ECKD. We can attach every device to it, they all talk (emulated) ECKD to the host, no matter what organization they have inside. Why should a large bunch of software be rewriten? By the time the conversion has finished, FBA will probably be replaced by something different. Remember: the break-pedal in your car still emulate the pedal on the post coaches that pushed a chunk of wood against the outside of the wheel. The real breaking infrastructure is hidden under the hood (literally in this case). Who wants to the pedal to be rewritten to control hydrolic breaksystems, with ABS control etc.?
