> Your latter paragraph seems a bit fuddy as people 'just dipping in and out' would never have to have contended with the iojs 'name' any more than Python/Ruby/PHP people have to switch to a different VM every time one is announced (e.g. PyPy/Rubinius/Hack).
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.
