I do like experiments!

What about going even farther and trying to integrate somehow into mesos?

Replace the hadooop executor, MPI executor with a 'VM executor' and
perhaps we
could eliminate a large part of the scheduler code (just a thought)...

Is the mesos scheduler sufficiently generic as to encompass all the
filters we currently have in nova?

IMHO some of these should probably have never existed in the first place: ie https://github.com/openstack/nova/blob/master/nova/scheduler/filters/json_filter.py since they are near impossible to ever migrate away from once created (a "JSON-based grammar for selecting hosts", like woah). So if someone is going to do a comparison/experiment I'd hope that they can overlook some of the filters that should likely never have been created in the first place ;)
