Something along the lines of World of logs, maybe? A way to capture and upload raid data to your character sheet, so that when people do gear checks, they can get some kind of Skill check as well. The Raid Stats was a great move, shows if people have the experience. Next logical step would be to show if they have the ability now, right?
Not sure how hard it would be to implement, but if it can be done, it'd be a nice one site one stop set up.
