I am using it between datacenters with handcrafted forwarding rules. And I am
using gluon which uses link local "multicast" mode [1].

I would call them batadv interfaces. And the thing behind it - maybe mesh
cloud.

I've already used both VLAN and VXLAN (and other things) for stuff like this.
But there can always be problems with your kernel/driver/batman-adv/...
version or even the hardware. And I can guarantee that all of them will
create some kind of cost (overhead, performance, ...).
Kind regards,
