Reading about SSL and haproxy, there will be some work needed for the haproxy configuration, see http://virtuallyhyper.com/2013/05/configure-haproxy-to-load-balance-sites-with-ssl/ but it's not really difficult.

I've also commented in the LB pull request to have better values for admin_host/public_host there. So in short, I would prefer to remove the TODO comment here and finish the SSL support in load balancer.
