Just thinking out loud here...

Stepper motors and actuators are fairly cheap. So are microprocessors and little lcds. Who's to say you couldn't make your own in-cabin damping controller like the EDFC or TEAS for your KW's or Megan's?

A parts list would look something like this:
two atmel butterfly's (one for the front and one for the rear...atractive because for $30 it includes an lcd, a user interface joy/button/and the microcontroller) (http://en.wikipedia.org/wiki/AVR_Butterfly)
4 stepper motors (http://en.wikipedia.org/wiki/Stepper_motor)
a lot of wire
wire insulation/heat shrink
some way to enclose the steppers and protect them from the elements
lots of time

(yes...I understand that I pitch a hairbrained idea to you guys about once a month)
