I'd just summarize it all up by saying that IPS is ready for prime time,
but not ready for auto-pilot configuration. It still requires
site-specific config and testing, and an experienced human running it.

Hitting the "Turn on IPS" button is just not feasible at this point in
time. In a few years, maybe. But certainly not now. (With any engine)
