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.
Sweet. Might I also suggest you pair a rating system with that? Going off of the age old "Gear Score=/= Skill Score", if you can get it to where parses can be uploaded, have some kind of system that takes X number of parses, and displays a skill number based on some criteria of your choosing? Could take from any number of things, such as, "Stands in the slime this much!" or "Hit by Rotface's Vomit this much!" etc. etc. etc.
