about:
Neat and useful jquery plugin which allows you to change any element into a single or multiple file upload tool. The plugin uses a mix of JQuery, Flash, and a backend upload script to send files from the local computer to the website server.

about:
Drupal smells like hell. For instance, it is notnatively possible to develop freely on a test site while still allowing content updates to continue on a production site. This small script allows you to maintain separate test and production versions of your Drupal site. After you've made configuration changes on the test site, this script can migrate them to the production site for you.
However, I'll pray while testing it :-)
