Subject: Distributing modifications to F80

As I know copyright law:  it does not protect the algorithm at all, only
the expression of the algorithm in code.  No problem there.  If only 20%
of the code is original, you also have no problem there.  I would say,
feel free.

If you want, I know a legal person who is knowledgable on copyright law.
If you would take a collect phone call, I can have you talk to her.
Send me a number and a time to call in you're interested.
