Portable Apache, PHP and MySQL!

I was curious whether such a thing existed for web developers/designers, and it does! Oh the joy.

WOS Portable by CH Software is a free portable Apache/PHP/MySQL server package which runs and fits on any USB/portable drive. The fantastic thing about this package is, it is totally customizable, and created on the fly; you can choose the exact configuration of your server, as well as preinstalled modules like Drupal, Joomla, Mambo, OS Commerce, Wordpress etc etc..

Very nice indeed!
