Some comments:

- I think the recommendation to require nbd 3.18 might be a bit strong
  ;-) I agree that 3.17 is horribly broken (sorry 'bout that,
  unfortunately my test suite didn't catch that), but older versions of
  NBD should generally work (although perhaps with less features). I
  would suggest you tell people instead to avoid 3.17 (or have them use
  the -nonetlink option to work around the bug).
- You compare NBD against the loop device. It might be interesting to
  note that the original implementation of the NBD driver in the kernel
  was fired off by doing "cp loop.c nbd.c"... (at least that's what the
  comments at the top of that file used to say, I wasn't there)
- I think the talk dives into technical minutiae fairly quickly; it
  might be useful to have a bit more of an introduction on why nbd might
  be a good idea.

It's a nice talk, I'd love to see it at FOSDEM (if I'm going to make it
there though, which might not be the case for personal reasons).

To the thief who stole my anti-depressants: I hope you're happy
