As Ciaran has said, if his derived work does not leave the server
then he isn't distributing it and thus doesn't need to release the
source. I, unlike the FSF, don't see a problem with that as he
couldn't give it to anyone else so there's no real risk for
If he is distributing it, he must distribute all parts of the
software in source form and must attach GPL license notices
unmodified etc etc. However, his extensions may not need to be also
under the GPL depending on certain factors, but whatever license he
does use must be compatible with GPL stipulations.
The GNU FAQ on the GPL is good on this, I'd only disagree with the
GPL applying across a binary boundary (ie; I can't see why a
commercial program can't use a GPL shared library).
