Can you please read them and tell me what you think? I have exactly what you wanted, and other people in the email group either said it is already there or not seems to be very much interested. Basically, i built to impliment some user space SCSI engines and initiators. If you want i can email you a working copy of it where you can present the normal files as disks.
