Based on this thread it'd require some work to upload test results to a remote server to validate them in Peril. (something Danger can do due to being run on the CI server, so it can read local files)
Until that hosting API is available, can one run Danger and Peril in parallel so that Peril does all the non-fs-actions and then Danger does all the fs-required actions? Would that mean we get two comments on each PR? Can we make them use the same one somehow?
