Of course the gut reaction to this is "why?" and the obvious answer is "because I can"... that's fine, but there's been plenty of filesystems built on protocols

Of course the gut reaction to this is "why?" and the obvious answer is "because I can"... that's fine, but there's been plenty of filesystems built on protocols or things that weren't really supposed to be filesystems. I remember way back when gmail first announced giving away 1GB of storage, there were a bunch of hacky things to turn SMTP into a real filesystem. So, I get the answer to "why make this weird filesystem", but I'd really like to know: why is this weird filesystem, weirder or more intriguing than the others that have come before it.
