   yes, that really sucks. fyi, "pang" is the sound cartoon guns makes in 
swedish. i guess way back, when the Erlang user base fit in an elevator, someone 
thought it was funny that ping could return pong (good) or pang (bad). and i 
guess it is kind of funny, but only if you speak swedish...

   yes, unfortunately.
   if you have two nodes, on the same machine, with the same cookie, running the 
same version of the distribution protocol, if should work.

   how about if you start the nodes like this;
erl -sname bla@REDACTED
erl -sname foo@REDACTED
