I was actually referring to WoW and Blizzard Live ID. I haven't played WoW since 2006, but my friend who plays told me that you can use Live ID to queue for instances with cross-server friends. He may have been mistaken; he quit WoW a few months back and may have misremembered or misunderstood the feature.

Either way, it seems feasible to implement a feature like that, even if no one else has done it before. The Duty Finder already pairs people from different servers together, so you would just need a system that pairs 2-8 specific people together, instead of just moving down a list of people who are queued.
