Maybe there is a complete misunderstanding what "network coding"
is?

Maybe an easier expression would be "packet mixing" or "magic packet
mangling" [1].

Any code that does something with networking is usually *not*
"network coding" (at least in this context here).

Have a look at the links Sven has provided earlier.

Just try it :-). Compile batman-adv *without network coding* with
your A-B-C scenario and see how it magically works, too :-).

[1]: Please no expert hit me :D. I know, ultimately, network coding would
replace packet based networks, if I remember Frank's talk
in Leipzig correctly
