The basic DNode example in coffee-script.

gru.coffee

#!/usr/bin/env coffee

# This one makes the call.

DNode: require 'dnode'
sys: require 'sys'

DNode.connect(6060, (remote) -> 
    remote.timesTen(5, (res) -> 
            sys.puts res )
    )

minion.coffee

#!/usr/bin/env coffee

# This one is the remote which answers the rmi.

DNode: require 'dnode'
sys: require 'sys'

DNode({timesTen: (n,f) -> f(n*10)}).listen(6060)
