If there were any kind of ether it would perhaps allow a universal positioning system, basically 3D GPS without supporting infrastructure that worked no matter where you went as long as the system could track you and periodically recalibrate itself vs some landmark. The more sensitive and precise the less recalibration it would ever need.

We can measure our speed and direction of movement against the cosmic microwave background, which averages over a much larger area than our visible Universe (if redshift is interpreted as light aging because of ether), but local measurements will be sensitive to local flow only. It's like measuring speed of wind to calculate position. It's possible, to some degree, if you have a map of winds, but its precision is extremely low.
