Yes, and thinking about it a little more, you sell it as a safety
device.
The reference to the local airmass gives you your current angle of
attack.
That's a pretty good safety device right there.
The longer-distance reference gives you what your AOA will be in, say,
200 meters.
(assuming the inertially-referenced attitude doesn't change)
That's a wind-shear detector.
For a light airplane making an approach at 100 kts, that's about 4
seconds of warning.
Is that something that could be sold to IFR pilots?
