Since @XVortex created a java payload version of PS4HEN that doesn't require you to push it using a PC, thanks to his web/java version, I have searched for a way to get this working without a web server needed.
It comes to my mind that PS4 supports BD-J (for Java) for it's Blu-ray Live (BD-Live) and that it has persistent storage and ability to do virtual storage as well.
PKG KitchenAID is super easy, you have one batch file to run and just follow the onscreen instructions. You can't go wrong. No need of a FTP client or to download separated tools. All you need is in the package and easy to use (will help some newbies).
