    My guess is; you'd need to write a virtual device driver that makes the OS think you have a normal disk attached. The virtual driver would act like a bridge between the OS and a RAID layer. This RAID layer would handle all the low level disk access. Read and write. The low level code would have to spread your files (including parity) across a minimum of 3 disks. Hope this helps. I don't have any Linux experience so I don't know how drives get mounted. So if anyone knows please correct me. :)
