panoramic retractable sunroof
 

I was watching 4wheeler TV today and they had one of the new Jeep Liberty's with the retractable canvas top which got me to thinking, has anyone ever put one of these in a third gen 4runner? I kinda miss the open air feeling and I am looking into maybe getting it back and keeping the runner with something like one of these.

Anyone have any experience or even seen one done?

This is the closest thing I've seen done before:
