Thanks for your detailed reply, Johanna!
Ok, I will give a slightly long answer to this. First - assuming that the

Yes. We are developing a module written by C++ that analyzes the traffic

Yes, as you mentioned, we do want a module that can be accessed and called
by every protocol analyzer. Regarding the "separate class that is
accessible by everyone",
where we should implement this module? Do we need put the C++ files in

Sorry I don't get the point of this part. In my understanding, wherever we
the plugins, it will be complied into bro's library /bro/lib/.../plugin.
What do you mean
(and how) "outside of the Bro source tree"?
Thanks a lot!
