I'd just take the cranks off and use an indicator afixed to the frame.
The only weird part would be to get the dishing right, but even this
seems pretty easy. Just find a flat surface, and when the wheel is true
somehow find a way to block it up with the spindle perpendicular to and
touching the surface, then measure the hight of the rim above the
surface in three spots. If they aren't even adjust the blocking until
they are. Record the average distance, flip the wheel over and repeat
the process. If all the measurements agree the wheel is properly
dished.
Or you could use a custom dishing gage.
