Thanks for starting this discussion :)

I've changed the subject line to open this up to the whole community, 
because I think we should be pursuing a unified approach to this across 
all OpenStack projects - there's nothing particularly special about Heat 
that would make it the only place to address this.

For those who have not been following, the FAQ linked above at 
https://etherpad.openstack.org/p/heat-build-info actually does a pretty 
good job of answering my questions.

For the record, I still find the answer to #7 unconvincing (random 
polling is your plan to find the rogue out-of-date server on your 
network?). Also, I have a better idea for #8, #10 is not quite as simple 
as it seems for boring (and mostly Heat-specific) technical reasons, and 
this thread is here to address #11.
