This is a tricky problem because for touch at least we do want the input
stream to be throttled to the display rate from the top level down.
Perhaps the answer is to enhance Unity8 to be a full-speed (non-
resampled) client and then the clients of Unity8 can then still have a
choice of whether they get resampling or not.
