Also, I think things get even funnier when you consider you don't

That, in theory, is not so difficult. Problems start in real life.
You could make six dipoles, one along each edge.
But with 4 inputs you can have only 4 independent signals.
Yeah, they are not linearly independent. I wonder how to map them... was
thinking you could derive those 6 dipoles independently (in the hope
that mismatches could then be compensated for more easily), and then
project each of them onto the XYZ space with a little summing matrix.
Not that I'd actually want to do that, though - with four MEMs, the
prize doesn't seem worth it :-]
