If you're talking about the built-in Erlang distribution mechanisms --
FWIW: in a quick test I did a while ago I had trouble keeping stable
connections for more than ~80 connected nodes. I must admit I was a bit
surprised as the "Efficiency Guide" seems to imply that the number
should be much higher (?). 

Possibly the number of known (but not connected) nodes can be higher
than this.

HTH,
