On further review, I'm not so sure about the practicality of it. In that paper they talk about the intrinsic storage capacity being 10Gbytes, but I think that number is in error. It seems it is 1Gbyte for the stated conditions (100mS round trip delay, 8 wavelengths @ 10Gbps). So in effect they're swallowing up this huge cross-country multi-wavelength network expense (has to be millions of dollars to enable this when you consider all the WDM equipment at all these locations), all to get 1GByte of "intrinsic" storage? And it certainly doesn't get any more cost-effective with scale, because scale means more WDM gear everywhere. If 80Gbps of provisioned WDM transport equipment--at a cost of millions of dollars--is sitting idle across the whole country, I don't think the guy who recommended this will keep from getting fired by saying "yeahbut, it can be used as a 1Gbyte cache by researchers doing distributed computing, studying extra-terrestrial life forms." But you never know. I bet they could get Corning to buy into this though....nationwide fiber farms, with thousands of miles of spooled-up fiber, packed into warehouses, all acting as delay lines....yeah, yeah, that's it....fiber farms.
