kschroeder / magento-namespace-autoloader

This is a simple module that allows you to use PHP 5.3 namespaced code in Magento 1. The most typical use for this will be if you are using a namespaced library in /lib in a Magento module. This module injects itself at controller_front_init_before and will be called before the native autoloader, but will only autoload namespaced classes thus leaving normal autoloading alone.
