Daughter visited this week.  They are looking for hardware.  I didn't tell her, but I think what they want to do is not possible.   They want a surface mount, two doors that roll in front and behind each other as there is not room on either side  for them to roll out.  Time will tell.  In the meantime, I have other projects.

 

They do make double track barn door hardware.

They make sliding glass doors that are ganged together.  If you move one past the second far enough the second one will follow the first one and so on.  Wife's cousin has an exterior glass door that has 4 doors and it works much like a aircraft hangar door. 

Keith, did she abandon the barn door idea?
