I guess it was a minor mystery that I had 0.2 working. I've gone through and purged the nvram and set wlan with it's own LAN ip. As long as I only run batman on the wireless interface things seem quite smooth and easy.
ff1# batmand -g 8 eth1 ff2# batmand eth1
It finds the gateway, there's internet access. Any suggestions for an init script?
In 0.2 I successfully ran batmand br0 and things worked fine. Trying that in 0.3 just locked things up.
