Ace,
The license preamble for Snort 3.0 provides some pretty concrete
examples of what we consider to be derivative works. While it's not an
exhaustive list and I don't think an exhaustive list is possible - the
preamble and Marty's public comments provide pretty clear guidance that
if you're modifying and/or redistributing Snort you should be adhering
to the terms of the GPL and licensing that project/product under GPL.
If you'd like to contact me either on the snort-users list or off list
and provide the specific scenario like David did, I'm happy to discuss
it and weigh in on the specifics. If I can't answer the question I'll
get the answer.
I will make the same promise to anyone else who has questions about
integrating Snort or ClamAV.
My contact information is:
