And other than these technical details, I would say that batman-adv is not a
very good protocol for 802.15.4/low-power wireless. It might need heavy
restructuring if you really want to use it in a deployment.
However, I'm pretty familiar with 802.15.4, therefore if you really want to go
ahead, we can even discuss further what batman-adv would need and what would
not.
