Re: including a wireshark view in propietary software

[Martin Visser <martinvisser99 () gmail com>]

Joshua, GPL does not stop anyone selling the software, but it protects
access to the source code. (Lots of people sell GPL software based
solutions, but as long as they provide free access to the source code (and
they can charge nominal costs for distribution of the source code) then this
is OK).
