This brings up another issue about applying GPL to ones own
code that has been subsequently redistributed.  Lots of
mods will be made to the code (and the owners of the mods
will perpetuate the GPL restrictions, of course.)  When
one wants to apply their code with the GPLed mods to a
*proprietary* project -- the original owner will have
to reinvent the GPLed mods...  But how does one do that?
If the original owner has seen the mods, the possibility
taint (seeing the GPLed mods) rears it's ugly head.
