to do that would be to release a Nessus 3.0 that shares absolutely zero of the

Not strictly correct. The Nessus crew, being the original creators of the
software, and copyright holders, can release all of *their* code under a
second and separate license at will.

Emphasis on *their*: all code contributed by third parties was licensed
under the GPL for Tenable, and thus must be removed from the non-GPL
version of Nessus. That's what Arnaud points out: there is very very few
parts of Nessus that were contributed by the outside community. Once those
parts are gone, "Nessus 3.0" can go on, even if it shares 95% of its code
with the GPL Nessus 2.2.5 initially.
