Me and my buddies have a server running the new Tekkit using the standard software they give you from here: http://www.technicpack.net/tekkit/
I've read the minecraft forum post Rei made and countless other Forum posts, most referencing a "plugins" folder, motd.txt files, and additional mods that need installing, all under the impression that you are running Bukkit (which we are not). Is there any way we can enable Entities Radar without having a Bukkit server? Or am I simply not looking in the right spot?
