I was just at Northern Tools, and I saw an annular cutter. Looks like a
hole saw on steroids to me. Being an old oilfield hand, annulus means the
space around the drill pipe. So, this would mean that this cuts out a
plug. Is this just a hefty hole saw, or does it have other uses?

We actually sell an Automatic Drill set-up for use with the annular cutters.
Automatic plug ejection and coolant and all. Works quite well even with
multiple spindle heads.

....and check out some of the related links by us.

We mostly use Hougen, but Jancy is a big, reliable name too.

With annular cutters, you can drill a deep, large hole (perspective is
everything) with much less HP. The cutters are expensive, but the HP needed
for a standard twist drill is more expensive.
