Hi David,

This is the code I using:

start_node(NodeName, Cookie) ->
	_Pid = spawn(os,cmd,[os:find_executable("epmd")++" -daemon"]),
	%% TODO: find something better than sleeep, to wait until epmd is up
	{ok, _} = net_kernel:start([to_atom(NodeName), shortnames]),
	true = erlang:set_cookie(node(), to_atom(Cookie)).

%% convert any sensible input argument to atom:
%%	i.e, atom, binary, list string, deeplist / IO-list
to_atom(S) when is_atom(S) -> S;
to_atom(S) when is_binary(S) -> list_to_atom(binary_to_list(S));
to_atom(S) when is_list(S) -> 
	try list_to_atom(S) of 
	    Val -> Val
	    error : _ ->  list_to_atom(binary_to_list(erlang:iolist_to_binary(S)))
