C,
One of the biggest reasons to not remove the modules and use jumpers to feed them is design. I look at the modules and the function they are designed to perform and think that performance can only be degraded by remoting them on the robot. You can use ribbon cables extensions for all of the interfaces, the DIO and solenoids work very well for this. The analog interface is a little more difficult since it has a power supply on it.
