I just got an idea for something that might be feasible though...

Say, you have a tracking system similar to EQ's where you activate the skill and you get a list of all the nearby things you're able to track. Click on a creature in the list to select what you want to track. Now, instead of showing you its location on a map or telling you which cardinal direction it's in, it gives a guiding line to said creature by the means of footprints on the ground. The prints shown could be representative of what type of mob it is. They could even go so far as to make flying creatures untrackable. It's immersive, feasible for incharacter stuff, and doesn't resort to using silly glowy beams of light.
