One alternative is a straddling platform that scaffolding can be mounted on. Works very similar to the Genie version, minus the need to put the heavy machinery on top of the straddle unit. All of it can be disassembled to parts and moved and put together on stadium-style seating by a team of 4-10 in a relatively short amount of time. They make models with wheels that can be rolled through the aisles to reach all the way across an auditorium.
