But yes, running multiple batman-adv interfaces on the same host works fine. I 
am currently using 8 in parallel. The lower/hardif/slave interfaces are using 
VXLAN (to connect some servers in other datacenters), fastd (to connect remote 
"clients") and some other "ethernet" protocol compatible things.

And the hard limit is most likely the number of netdev's the Linux kernel can 
create (id wise and memory wise).

I don't like the word "namespaces" here. Because this reverse to a completely
different concept in the linux kernel.

And I don't know what you will end using - so I cannot say if this will work
or is tested.

Kind regards,
