[Battlemesh] tests for WBMv3

exactly. Lets keep in mind that the boxes are CPU and memory constrained. I 
see no problem running two protocols, given that the protocol implementation 
is usable. In order to compare convergence with mobile nodes this the only 
feasible scenario, IMHO.

We have been running up to three protocols simultaneously in a production 
environment. I have seen one issue so far: If you try to saturate the links 
the WLAN TX buffer might overflow and block transmissions for all test 
candidates. This can be addressed by tweaking the test protocol.

A good argument against running more than two protocols at a time.
