Could someone clarify on this? We're planning to have a network with a
large number of nodes, but the average traffic is probably not going
to be very high. So we'd probably hit any limit on the number of
tunnels before we run out of steam on the encryption.

On the inverse, what's the maximum average traffic anyone's seen on
this list. I'm asking about both real-world, and simulated.
