As I understand, overhead of Erlangs' fully connected node network is in
TCP pings or heartbeats that nodes send to each other. Each node pings
every other node that it is connected to. So that ping overhead grows
quadratically with node count.
Frequency of those heartbeats can be set with -kernel
We've got a riak_core based application in production which currently has 83
and which at one point had 85 nodes so the practical limit is definitely higher
than 20. It would be nice to know of a real limit though...

Hi Sharas,
Erlang/Riak do
