I would be interested to see an example of that Chuck

Assuming Marius and I fairly understand LTIs, how would we end up
with coefficients for Biquad starting with units like mass, Youngs
modulus etc?  

And biquads are quite efficient, so if we had a little helper abstraction 
that calculated an MSD type behaviour that would be very nice.

If I remember the msd externals are bit hungry.
