Okay, good. So to Bob's most recent point, let's try C:

C. You may:
	a) redistribute the unmodified source code freely under the terms of 
this license
	b) create binary versions of the original source code, which can be 
redistributed freely
	c) create modified versions, which can only be distributed in source 

How does that rate?
