That's fantastic.  Please feel free to ping us whenever you have any
questions on getting this running, or any feedback about how well it
works for you.

Right, this isn't very flexible right now, but will be possible in the
near future.  The way that this will work is that we'll put that
information in the formula metadata itself, so rather than the user
having to select where the formula has to run, the formula author will
have a saying on where he designed it to work.  It may make sense to
enable a forceful switch too, but that's a more advanced option which
may break things more often.

This is very realistic, except I would say minutes, rather than days,
assuming the IaaS piece is in place.  Ensemble was designed after that
kind of use case, so it fits really well.
