Meraki are also doing mesh related things with the APs etc.
Its my understanding (not that I've had much time to play) that mesh
has improved greatly over the last couple of years with developments
like BATMAN which is now in the 2.6.38 mainline kernel. I suspect pure
IPv6 might also assist with some of the problems seen with broadcast
on mesh networks as they get larger simply due to its lack of it.
