It does sound like an interesting option for PVPers. But as someone who doesn't really care for PVP all that much (well, not against other factions; some of the players in my own faction, those are the ones I want to kill most of the time!), it doesn't seem like it'll contribute much for me. Maybe it'll let me know where some of the more annoying players on my own faction are so I can avoid them out in the world? I don't know.
