This second requirement may be counterproductive, depending on the OP's
aims.  If he is trying to push the social agenda of free software, then it
makes sense.  If he wants the world to get the maximum benefit from his work
and is seeking at most recognition for it, then this is too restrictive.

Here is what I use for most of my publicly distributed PIC code:

It's plain, simple, and asks so little in return for using the code that
very few people or organizations will find the cost too high.  This
maximizes dissemination of the code and thereby its overall usefulness.
There is also little incentive to cheat.
