I made a really simple loadbancer (using HAproxy) in Heat
(https://github.com/heat-api/heat/blob/master/heat/engine/loadbalancer.py)
to implement the AWS::ElasticLoadBalancing::LoadBalancer but
it would be nice to use a more complete loadbancer solution.
When I get a moment I'll see if I can integrate. One issue is
I need latency statistics to trigger autoscaling events.
See the statistics types here:
http://docs.amazonwebservices.com/ElasticLoadBalancing/latest/DeveloperGuide/US_MonitoringLoadBalancerWithCW.html

Anyways, nice project.
