I wonder if you can invite your RealID friend, then hand leadership to someone else, then have them invite their RealID friend.. because they did mention they have to be on YOUR realID list..

Probably, yes.

Dude, stop stimming, I can't hold aggro when you do that!

Hahaha! That's great.

Assuming this will cost additional cash money (it will!), there's not a lot of value right now. It doesn't work for battlegrounds or raids, or even regular questing. And I can't even test it since I have nobody to invite and it wouldn't let me invite Abric's dwarf.

We could make a couple low-levels and test it in RFC?

Leading a Real ID Party / Dungeon Finder
It should be restricted to you (as the party starter) as the primary Real ID holder and passing the group lead should not allow the other person to invite additional RID people of their own. That's my understanding of it and why we updated that question a bit to make it more clear. Now, should you find that it's working otherwise, I'd love to hear of it.

Essentially, you as the originator of the group have Real ID. You have friend A on one realm and friend B on another but you're RID friends with both (they would need to have RID enabled too), even if they don't know each other, you can invite them because YOU are RID friends with them both. You can then invite additional people from your own realm (if you don't have any other RID friends to fill it in with) and go into the dungeon, or you can choose to enter the Dungeon Finder and let it do the work of filling in the rest of the group.

This is my current understanding and it should be functioning this way. (Blue Tracker / Official Forums)

Ahh ha!
