Yes, but I think that securing ARP is only a small part of securing layer-2 
against redirections and mallicious traffic. And its a pretty unimportant part 
for mesh networks.

You don't need ARP-spoofing in a wireless net, because you don't have a switch 
there to isolate the nodes from each other. If a node is in range, it can 
always overhear your communication. And it can always pretend to be the valid 
ARP of the valid node.
