There were plenty of times the simple turntable in Les Mis would break down and they'd switch to B mode.It's impossible not to imagine epic productions like Miss Saigon or Lês Mis using this kind of technology.
I can't imagine how they expect this all to work consistently. Imagine the tower stops right in front of your seat and they can't move it.
Tho, it'd make a nice upgrade to Carousel of Progress!!
