How about something like the British Leyland Hydro-spastic? With a single oil reservoir, it'd be nuts, crap, oh and nuts.

It is possible to create a shock absorber from magnetic fields rather than oils, and the possibility is endless. But for me some of the enjoyment comes from the tuning of things like shocks, to remove this would remove it as a tuning factor, and remove any reward for making the car handle extremely well.
