Thanks for your input.

I had a quick look at the website to get an idea but I had to notice that 
there is quite a collection of daemons, kernel modules and apps. As you seem 
involved in this project, could you point us to the collection of tools that 
you think we would need to achieve the following:

* sending protocol traffic
* transmitting the routing logic
* encapsulation of the various packet types (see http://www.open-
mesh.org/browser/trunk/batman-adv/packet.h to get an idea)
* directly influence the traffic flow, i.e., ARQ for broadcasts, interface 
alternating, bonding, forward error correction, etc
* layer 2 fragmentation


Cheers,
Marek
