I am not a lawyer and can not advise you of this, please work with yours
to set into place the requirements you will have to keep this working
properly.  Note, it is not trivial, and will require work on your end.

I will push back again, and ask "Why?"  Why do you want this dual

licensed like this enable you to do that having it just under GPL-2.0
will not?

You all have ways of posting code publicly :)
