Starting today, Volery (now called Ninite) is available for everyone. You don't even need an account, simply go to it's website, select the applications you want to include in your installer and then simply download it.
The basic version is free for personal use and will remain so, but the Ninite developers are planing to add a premium version. Until then, advanced features like caching downloads to save bandwidth are free too. Details about these advanced features, HERE.
