Does the license only apply to those to whom the binary has been distributed
to? If the plugin is never publicly released, does the license imply that
only the receivers of the plugin are required to be sent the source code?
If the plugin is never seen by the public eye, does that imply that the
source code may stay private as well?
I've never been in a situation like this, so I don't quite understand the
intent of Wireshark's license for this kind of scenario.
