IPVS is fast and has been part of the kernel since forever.
It would be cool if we could use it instead of iptables (and the userland proxy).
This may also resolve issues seen with hairpin nat on iptables.

See https://github.com/kobolog/gorb as a working daemon that uses ipvs for load balancing...
We'd use it like this except there's only one backend.
This could potentially be utilized when there is some service level concept as well.
