A good start. ;) 

So, what other information do we need to make this generate (most if
not all of our nagios configs)? 

I'd guess:

- vpn info. I'd like to get our vpn info in there so we have the right
  dependencies so we can only get one alert from a site being down
  instead of 10. ;) 

- contacts

- services - perhaps we could populate these in infra-hosts too? Not
  sure how best to do this. 

I guess the next step I would say is look at our current nagios config
and see how we can autogenerate the rest of it, or at least the parts
related to machines.
