I would have to say that it is pretty clear to me as well. From a
copyright point of view, ClearSight's product will not run without
Ethereal. It depends completely on Ethereal. It was written to build on
top of Ethereal. Therefore it is a _derived work_ and clearly must fall
under the GPL.
My thinking is that our next step in this matter is to get Eben Moglen of
the FSF to talk to them, or initiate a lawsuit.
We do not need to assign copyright to the FSF to have Moglen look into the
issue and call ClearSight. They acted on the Samba team's bahalf some six
years ago when a company tried to sell Samba as their own product.
