title: shasum for npm releases?
body: <p>I am trying to install node.js on Windows 7 without admin privileges.  I found instructions <a href="https://groups.google.com/forum/#!topic/nodejs/6tsV6ZA9RC4" rel="nofollow">here</a> which suggested downloading <a href="http://nodejs.org/dist/latest/" rel="nofollow">node.exe</a> and the <a href="http://nodejs.org/dist/npm/" rel="nofollow">npm.zip</a>.  In the directory for node.exe, there is a reassuring <a href="http://nodejs.org/dist/latest/SHASUMS.txt" rel="nofollow">SHASHUMS.txt</a> file, but not so for the npm.zip directory.  Are shasums available for the npm distributions?</p>
