I mentioned to Dellphi that it would be neat to have the ability to chat with other players in-game, even when I wasn't in-game, via some sort of chat app. Today he sent me a link to something called "Dynmap", which is some sort of Bukkit plugin thingy. He pointed out that it also has a real-time map feature.

pretty keen, huh?
Not sure of the server load this would present, but I think you can contain the interaction to your whitelist of players...
