Regarding the code cloning:
youre my_tora cloned agents can either
- talk only to other my_tora agents;
- talk to my_tora agents, but also to unmodified tora agents;
in the first case, you can simply duplicate all references to tora, which
will duplicate the packet header tora into my_tora. Then youre my_tora
agents will communicate using my_tora packets (eg, by using "hdr_mytora" in
the new my_tora agents)
(this is very ueful for trying things while keeping the original protocol
100% intact).
In the first case, you need to use the original tora packets, and you can't
change them because of compatibility with regular tora agents. Thus, while
you should clone the agents into my_tora, make them use the regular tora
packets (eg, by continuing to use "hdr_tora" instead of "hdr_mytora")
