Only members. The MW and AAC have, and possibly others, but no big time conference. I personally don't see it happening, unless FBS football totally separates and becomes like it's own division, Erich I don't think will happen either. The more I read about how expansion really happens, the more I believe university Presidents want the entire school to be a part of their conference in every way. IMO BYU will have to add some serious TV money for them to consider it. That's the only way I can see it happening.
