• Prefix all classes with Horde_ that don't have that prefix yet (also see http://www.php.net/manual/en/userlandnaming.php).

• Global Prototype/Scriptaculous libraries.

++ To discuss

• use __autoload() instead of require_once

• Using a global __autoload() function is not good practice for a framework because you can only have one __autoload function - I'm not in favor of it (ChuckHagenbuch).

• Using it in Horde apps as opposed to the framework is an option, but still leaves us all of the framework requires.

• http://php.net/spl-autoload-register is a potential solution. With PHP 5.1.x (or 5.2, or ...) as a minimum version requiring SPL should be okay.
