Its not a question that needs to be answered now, but I don't see
how model #2 is consistent with the open-source model of doing
stuff. (I'm being intentionally vague there as many devices are
sort-of developed in an open-source manner.)

If there were a way to base things on a PKI for manufacturers that
worked for open-source communities that'd be really good, but I
don't think I've seen such a thing proposed so far.

I'm also very very unsure how model#2 might work in the face of
equipment being end-of-lifed by very small companies or what
happens after a teeny-tiny manufacturer goes bust.

Were the anima (or homenet) WG to try address those questions,
I think that'd be great. (And to repeat, I'm not looking for answers
right now, but just to see that a WG will commit to tackle this.)
