[erlang-questions] How to send a message to all nodes without UDP broadcast?

[Johan Montelius]

A word of warning and: rpc:abcast/1 is not atomic multicast as abcast  
normally refers to. It implements a basic multicast. If the sender dies  
you might have a situation where only some of the processes have received  
the message. This also goes for the list comprehension solution and also  
for how the pg module is implemented. The pg modules does however give you  
a total order of message delivery something that rpc:abcast does not.
