Except we already do: https://github.com/cloudfoundry-incubator/pat/blob/master/benchmarker/local.go#L26

The problem is we don't actually ever display results from a benchmarker anything. We display samples that have stats from a csv poured into them as "live" results. So, I can move the error encoding into store instead of server, but it's still not going to be in benchmarker.
