cool!

I don't really understand where you see the "new" challenges. If you require 
static IP addresses you can deal with that in the same way you did without 
batman-adv. You could configure alias interfaces, calculate an IP out of the 
MAC or even use DHCP to assign always the same IP address to a certain client.
How your setup looks like very much depends on your requirements.

There is no special handling yet (expect for the ARQ mechanism for all 
broadcast packets). I also suspect that ARP requires some more attention but 
nobody has done that so far.

Cheers,
