I have not seen *any* ready-to-use of meshing so far that is very scaleable.
In order to scale, you basically have to limit the depth of routes you
discover and the length of routes you take. Otherwise in average, everybody
needs to forward more data compared to the amount of data end nodes can
send/receive.

How do you intend to do this in netsukuku?
