I'm writing a web app that has a PHP/JSON backend and a very javascript-heavy front end. After spending some time in JS, it really sucks going back to PHP, as the language itself lacks so many things Java/ECMAScript has. So the idea is to be able to use EMCAScript as a backend programming language with the ability to access files, SQL databases, sockets, do system calls etc. Since its too much work writing these from scratch, the project could be a cross "compiler" between ECMAScript and Python (or any other suitable language), so that people can write web software in one language only.
