We would take the high res geo, reduce it, then run a custom script that generated nulls that were cluster constrained to the points on the geometry and simulate it, then envelope those points onto out the high mesh. This was one of our work arounds, depending on the shot and what was needed, but this solution seemed to work pretty well, as long as your create the geometry from a default flat position and then simulate into position.
we tried cage deformers on some things, but found the size of the cage deformers to be huge compared to the enveloping. I think each situation calls for different approach. Found that some times you would get great results with one method and then the same method would create horrid results.
