It's even easier than that:

	nodeid = atoi(getenv("NODEID"));

This is subject to spoofing of course, so I wouldn't use it to try to node
lock a particular piece of software.  It's actually more complicated than
this, since the node id is hex and atoi wants decimal, and good programming
practice would require a bit more sanity checking.  But you get the idea.
