Chris, the chainring is a special spline mounted one on the Panasonic unit. It would be possible to have a dual or triple special, but very unlikely for two reasons. The chaindrive relationship between the motor and chainring would be changing all the time, altering the character of way the power applied and that would disrupt the riding rhythm. Also the mounting of the chainring isn't directly on the pedal shaft but on a freewheel collar with it's own bearing. I don't think that would be stable and long lasting with multi chainrings.
There is a very fast version of the Panasonic made by BikeTech, the Flyer S, where speeds in the order of 20 to 30 mph are the norm, so that's a possibility, motor and pedal based speed performance rather than pedal only based.
