AddOn Idea: Auction House iLevel Column

Just a  quick idea for any addon writers out there, which I give to you free. I claim no intellectual ownership and want no public thanks.

I would like a sortable column on the Auction House that displays the iLevel of armour and weapons as is done within the Auctioneer add-on shown above. The thing is I don't want to use an add-on the size of Auctioneer simply for a column on the AH, when IMHO it should be a standard feature of the AH.

A while back I did look through the code to see if I could spot it but I failed horribly and am not gifted enough with lua to even hope to do this myself.
