Yes I thought this looked interesting, there are a few reverse proxies/servers written in Go now as the standard library makes it pretty easy.

I was wondering if this could be used instead of load balancers on a VPS (for example on providers like Digital Ocean or Linode). The only thing it is missing that things like haproxy provide is failover to another load balancer if there was a problem, otherwise it does add a single point of failure, not sure how simple it would be to add that.
