In the BarBOF I tried to explain my belief that there is a place for in-place
(not double/triple buffered) firmware update, via some kind of setup-process
followed by a very constrained CoAP/DTLS/OSCOAP Block Transfer mechanism that
a recovery bootloader could run.  I imagine pretty much *all* the protocol
mechanism being cached.. (ND, IPv6 addresses, DTLS setup, etc.)

So I wrote up my challenge, and my straw-man concept of a solution.

Please disagree with me... preferably by sending text (or pull requests):

Ignore my strawman, or perhaps, provide your own.
