I don't think this feature is available by default. But a small change
will enable you to do that.

The following is in ns-lib.tcl, 
Simulator instproc node args {

	....
	set node [eval new [Simulator set node_factory_] $args]
	set Node_([$node id]) $node

>	#set the nodeid in c++ Node 
>	$node nodeid [$node id]

	$node set ns_ $self
	$self check-node-num
	return $node

...
}

I will check this change in sometime soon, but till then you can do it
yourself, and recompile.

Now the nodeid can be accessed by node->nodeid(), this method is already
defined in the c++ code.
