The great features of this lift could be that they will allow acceleration and deceleration at much higher lifting speeds than a normal cable driven elevator.  Also it means that a level on a building could have a elevator that comes Up to your floor then travels accross the floor to your door.  No need for hallways in buildings using this design of elevator. (admittedly the hallways would be elevator / lift ways instead.  (I would say this is an elevator more than a lift, even though I am from the UK. Lifts are pulled, elevators are driven.)
