Precisely. The JVM class loader already provides that functionality.
Say for example, you want the various math functions, you have java.math
loaded. If you want a fancy package that interprets the raw sensor data
for you, load RCX.Sensors.MultiplexedTouchSensors (or whatever).
You could certainly implement this in any other interpreted bytecode, there
is nothing special about JVM in this regard other than it already has the
functionality.
