Buried in the code are several programming strings that hint at big changes to the WoW Recruit-A-Friend program. At the moment all the program offers is a few days of extra play time if your companion opens up a subscription. The strings, though, suggest that someday your referred friend may be tied much more closely to you. Hints are there that you'll be able to teleport your friend to you, that recruiting a friend may increase your reputation with certain in-game factions, and even that you may be able to grant levels to your friend's character. If these additions to the game are to be believed, this system will have limits; you won't be able to teleport your friend around beyond a certain level, and characters that have leveled past a certain point will no longer be able to have levels granted to them.
The notes also imply that your own character's level is somehow tied to the number of levels you can grant a friend; perhaps some sort of metacurrency. This is fascinating news, if true, and hints at the possibility of even more changes coming to World of Warcraft in coming months. Certainly here at Massively we've been talking enough about subjects related to this; it's wonderful to see Blizzard coming at the problem of the endless grind from such a unique angle.
