So is there some userspace part to go with this now?

FWIW I've not looked into it - is it just a case of someone knocking out 
some JSON from the MMU-600/700 TRMs, or is there still mroe to do? 

That should just be it.

I had 
the impression that *some* part of the process was stalled until 
implementations can start providing meaningful IIDRs, but I wasn't sure 
whether that was tooling or just data. I just work the low-level 
enablement angle :)

Tooling should be ok, but I would just like to see more of these JSONs 
so any tooling issues can be ironed out.

Cheers,
John
