Is there a easy to use Mesh add-on?

So, in a pure mesh network, the backhaul is wireless.
In a cabled network, obviously it is "cable".

@lleachii

Mesh can be WiFi and Ethernet (OLSR)

In OLSR, an Ethernet interface can be meshed too.

But the OP seems to be specifically referring to roaming-WiFi-type meshing - not "mesh routing". *

*-E.g. if all devices spoke OLSR, it would work too for the OP's use case.
