Via Sitepoint, J4P5 is a "JavaScript interpreter written in PHP 5, that allows to run untrusted scripts in a sandbox on your server. It aims to implement most of Ecma-262 3d edition."
There are a couple of demos here.
A bit of a shame that you need PHP 5 which rules out its usefulness for many people but looks like a very cool and promising project.

It’s also a shame I can’t even try out any of the demos. Do you know of anyone that has these running on a correct PHP5 server?
