&gt; Your latter paragraph seems a bit fuddy as people &#x27;just dipping in and out&#x27; would never have to have contended with the iojs &#x27;name&#x27; any more than Python&#x2F;Ruby&#x2F;PHP people have to switch to a different VM every time one is announced (e.g. PyPy&#x2F;Rubinius&#x2F;Hack).<p>One of my main use cases for Node is Zombie, and that required io.js after v3. No mainstream PHP, Ruby or Python application has required a different interpreter.
