Edit: Heres another idea as well. How bout we take some of those spells we dont use, and put them to use for this if it ever happens? I'll give an example.
Say using inscription you can create a scroll of fog or something. This could be used to combat a Seer's stone which could be made by alchemy. So in order to get coordinates of someone they must use a resource, this seer's stone which costs around 5k to make, but if someone is under the effects of a scroll of fog (say it lasts 10 minutes per cast, around 5k to make as well) they will perhaps get incorrect info or a blurred vision of where they may be. You get where I'm going with this, if PvP'ers want this tracking ability they can at least be using it in an RP friendly way.

Edit again (sorry I hate doubleposting): I'm not sure if it would be possible, but instead of giving coords, maybe use the treasure map system? What I mean is, uo generates those tmaps from its same map file as everything else uses. So it could be made I think to return a small map of the area the person is in. This could be beneficial because rather than coords its showing the area, the pk'er seeking his victim would have to take a moment to think on what area it could be etc.

I really like these ideas. If it was ever to be added I think a way to always stay hidden, at a cost, is acceptable. This allows for players who do not wish to pvp a chance to stay out of it just like before but with a minor cost to them. The only thing I could add to this idea is, if you track someone you cannot use the hide ability for x amount of minutes and if you are hidden with the fog item, using the tracking item would reveal you.

As for the tmap thing, that would be awesome. I think it would be very cool if instead of using the web page you went to a fortuneteller npc and they gave you the map at a price. Maybe have this npc say "I can currently see 12 beings wandering through the world, who would you like me to locate?" and a gump would pop up with the possible players that could be tracked. Once you select it, you get the map and are on your merry way to scalp them.

Just my added thoughts on some great ideas.
