	memcached is just a hash table.  For example:

	Map<Integer, Node> m=new HashMap<Integer, Node>();

	m.put(n.id, n);

	Can you get n.next in that example without doing another map lookup?

	Furthermore, it doesn't attempt to understand the data you're giving  
it.  The value is a blob and memcached can not and should not  
understand what it actually means.
