I saw the down votes almost after submitting the link. How it could be wrong or stupid from technical view? Multiple and concurrent isolates was something supported by v8 for a long time. This is a distribution benefiting from that instead creating multiple processes. Besides, the code protection looks interesting. If this is something you need for your node solution, you can simply download and use it. Its free..
Gents! Isn't it too early to say something? We needed this feature for our product development. It worked for us hence we thought it may work for others. Besides, Multithreading is not the only thing comes with nodeJX. We implemented other things and wanted to share with the public. We love node.JS! and want to do more with it. Thanks!
