The entire packet stream generated is a proprietary system on top of
TCP and UDP that consists of avionics data, all of which is considered
proprietary.  There are several hundred different packet messages that
contain one to several hundred data elements.

I was curious how the license Wireshark uses applies to this scenario,
since I've created a DLL to process data that is also distributed to a
govt entity, but I'm using an open source project with a GPL license
to translate this data, but the source code that translates the content
they want to keep private.

Regardless, there's no way I would be allowed to submit this plugin to
the public Wireshark repository (not without serious legal/employment
consequences), so maybe its a moot point to discuss.

Best regards,
John D.
