Soitenly. Here's a cool site with a video showing their router jig. Pretty neat.

Also, was just reading up that the some jigs will work well with a drill press, but the issue is side-load on the chuck and potential injury (drill presses don't like side-load).
Drill presses weren't designed for side-load, but with the right types of bits and jigs, it can be done, slowly.
