It is, but the same system is available from INTAMIN (who built it for Disney)
Intamin had nothing to do with the Soarin' rides. A WDI imagineer invented the concept and a steel mill in Vancouver, BC build the giant erector sets that lift the cars in front of the screens.
Vekoma and Huss already built copies of it. I tried the Vekoma version in Taiwan and it was a nice concept. Basically, to get around the erector set patent held by WDI, the Vekoma version loads in a room and then your suspended car just move forward in front of the screen. Nice images and the suspended car had side movements, as opposed to Soarin;. Huss sold a few ride systems similar to it in China and I believe one in Taiwan.
