Cross server friend-adding/queueing for Duty finder.

Me and the wife ran some dungeons w/ a few people we would've loved to add to our friend's list and group w/ again. But alas, they were on a different server and it was just not ment to be.

So I was wondering if anyone knows of any plans to impliment cross server friendslist/queueing for Duty finder. I would ask for an option to "requeue with same group" option at the end of a dungeon. But as hard as it can be to find a tank sometimes, that might screw over queue wait times a bit.
