I just want to point out that the use of the virus metaphor to describe
the legalities of association in relation to the GPL is inappropriate
because the "infection" does not proceed beyond one level.
GNU GPL V2: 2.
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
It's more of a proximity effect. So we need a new metaphor.
Perhaps we could talk about the GPL Freedom-Force-Field (GPL F^3 ?)
or something like that :-)
