Now my understanding of these types of contracts is that they don't limit or 
constrain new, non-derivate works which are combined with the original 
works.  I could for example write a whizz-bang physics module for STAGE and 
keep that work's source private if I so choose, so long as it was not a 
derivative of earlier GPL/GFDLed work.
If someone wanted to distribute a CD with WF music and their own 
compositions, they could maintain private copyright over their works (again, 
as long as they are not derivate works), but they would be required to 
maintain the GPL/GFDL copyright requirements on the WF works.

This is true, correct?

If I am incorrect in this I would appreciate knowing; and an explanation of
