    Nanosecond latencies and disturbingly high throughput are already
    possibly today :) Consider the battery-backed RAM gadgets that present
    themselves as ATA devices, or nbd over 10gige network.

    In fact I'm about to strip down drivers/scsi/sata_promise.c to a driver
    that just talks to the DIMM, and another else: drivers/block/pdc_mem.c.
    At that point you're really just looking at the PCI bus and RAM limits...
