Just put a link tag (with rel="canonical") in your document's head to point to the canonical version (with or without the www, whichever you prefer, just be consistent). Then the search engines won't hurt your rankings for letting your users browse from either URL.

The same can be done for many other situations in which you may end up with "duplicate content": http://moz.com/blog/canonical-url-tag-th...e-sitemaps
