Tom, I was careful, as you noted, to say it would work for a Baron.
The only prop driven single I can think of where it would work would
be a Lake ('prop driven' is intended to take SE jets off the table!).
I suppose you could put 'tells' out on the wings of SE prop driven
airplanes, but somehow I don't think I'd want to be looking at the
wing to figure out if I was coordinated.

Tony,

Those glider guys
who tape a piece of yarn to the middle of their windscreen never have
to look at the ball, do they?

The yarn is the (much more sensitive) equivalent to the ball, but it
obviously only works in the absence of a prop slipstream. Might work on
twins, come to think of it.
