I hadn't imagined this as simple chair simulators.  I imagined it as a room of ten or twelve modules that were networked.  Each Mechwarrior was enclosed in a 'basic configuration' of a mech cockpit and basic or detailed profiles can be loaded into the simulator to give the warrior the feel of driving their own mech.  The modules are all designed to simulate movement and resistance the mech creates to the most real degree without being in an actual mech.
