If you only care about Linux, then you don't really have to worry about the IP
addressing scheme, since a node can just broadcast 255.255.255.255 to find
neighbors.

But with Mac OS X and I think BSD also, broadcasting 255.255.255.255 does not
go out to all network devices, so its functionality is limited.  Basically, to
ensure that the broadcast will be received, mesh nodes need to be on the same
subnet.
