Bird's eye view: you have a block device, for example /dev/nda. It
acts like any other block device, which means that you can create
a file system on it, make it part of a mirror or RAID 5 array and
so on. But the actual hardware is somewhere out on the network.
Most likely a *local* network, of course. Maybe someday
you could do this on a public
network, but local is scary enough. The bug list for this
project makes you wonder why anyone would even think about
deploying it for important data - it just goes on and on
and on with hangs and crashes. Sounds like a great way to
spend the weekend, doesn't it?
