Comment:

 This is amazing!

 I've done some testing and haven't found any problems:

  * Used nb-secure to blast a signed image onto 10 secure laptops from USB
 (used 4 key salute)
  * Without booting those laptops into OS, used save-nand on 3 of them.
 Verified that .crc files match, and verified that sha1sums match and also
 match the original fs.img which was blasted from the "server" XO.
  * Used nb-clone to test blasting-from-own-NAND, used an unsigned image,
 confirmed that the resultant target system could boot after and had same
 name/colour/journal
  * Tested nb-secure1, nb-secure6, and nb-secure11 as channel overrides.
 Confirmed that the "ether:" printout on client side corresponded to
 overridden channel on server.
  * Tested changing redundancy by setting to 1% on server and choosing
 busiest channel... noticable degradation in performance on client side,
 but it completed eventually.
