As one of the core reviewers who couldn't make the summit, this sounds
like a very exciting direction to go in. I'd love to see more docs (I
realize it's still early) on how mesos will be utilized and what
additional frameworks may be used as well. Is kubernetes planned to be
part of this mix since mesos works with it now?
