I think the mini-map idea both has merit and is not overly CPU-intensive. I suppose it would be similar to teams that use line overlays in aligning their shooter. If you keep the total x and y components (or r and theta, whichever floats your boat) as variables stored on the robot, it should be a relatively easy task to use those values to add a point image overlay to a stock background map on the dashboard. The overlay would probably not be that taxing, provided you are careful with your implementation.
