Can you create a way-gate ability which only works for the owning player?

Possibly with triggers. If a unit leaves a region of one waygate and immediately enters the region of another that unit must have used that waygate (or a long range teleport spell...). In such a case if they are not the correct players you can force them back by setting their position. It still will not stop the pathfinder from trying to use the waygate though so it is not a perfect solution.
