What do you mean by "don't have local networking"?

I thought the loopback network interface is a given.

Sum it all up, double it, and see if you can still swing that on your current network backplane. If not, buy a bigger network, or start working on ways to compress/reduce the data stream :-)

I would also keep in mind that messages between Erlang processes and inter-node "kernel pings" go over the same socket. This means that pings start to lag as the message traffic gets heavy. Erlang nodes split when pings are significantly delayed and then in your in deep doodoo. 

This used to be a case a couple of years ago, I don't think anything changed since.
