Wee have that in zbrush, it has  a slider for the amount of detail that 
is preserved, though if to low it will make you dizzy from seeing the 
mesh change so much.

Another idea in addition to this would be to use normal maps constantly 
so it still shows the detail even while in lowpoly view mode.
