More Nonlinear

[chordman at flash.net]

Is nonlinear feedback in a filter viable?  I was thinking of 
the possibility of voltage controllable nonlinearity actually.

Perhaps something like a starved tube in the feedback path where
the starvation is voltage controlled.  Or perhaps a filter with
switchable nonlinearity elements in the feedback path, these 
elements may perhaps also be controlled by an external voltage.
Or would something like this just oscillate wildly or go 
randomly chaotic too easily?
