Martin,

You probably want to look at the new R8 feature for hidden nodes.  
>From the R8 release notes:

	Kernel
	
	Hidden Erlang nodes and hidden global groups have been 
	introduced. This makes it possible to establish hidden 
	connections between Erlang nodes. See global_group(3) 
	and erl(1). 

	The distribution mechanisms are generally improved to 
	meet demands for larger networks of distributed Erlang 
	nodes.

There was a thread on the list in April starting here:
