Doobrey was working on
something similar. And I think Jens' original idea for the Kickflash was something like this (the product that shipped was different, though). There's also
this for the A500. It'll be nice if this gets into production - the idea's been around a long time, but never commercially executed. I hope it can hold more than just Kickstart - would be great to get something analogous to the Algor or Deneb FlashROM so that it can hold Poseidon and other ROM tags.
