Also regarding a mob tracker - the codebase for auctions on my site (including the realtime log uploader) is done from data placed on the player's hard drive in their log file (by typing /log on or whatever in game).
I had considered a mob/player tracker in a similar manner, it would not be difficult for someone (or myself) to modify the log upload code (its open source and on my github and website) and use it for whatever you like.
