Here's another idea that you could do with the autoloader.  The autoloader
is slightly modified from PureMVC's site to suit my needs.  Using namespace
and everything that's PHP v5.3+, this is part of PureMVC framework that I've
ported over from the original Flash code a while back.

define( 'PMVC_BASE_DIR', str_replace( '\\', '/', __DIR__ ).'/' );
function __autoload( $class )
{
    if( stristr( $class, '\\' ) )
    {
        $file = APP_DIR.str_replace( '\\', '/', $class ).EXT;
        if( file_exists( $file ) ) require_once $file;
        else  throw new \Exception( 'Unable to find class '.$class.
                ' in the expected location '.$file );
    } else
    {
        $_basePaths = array(
PMVC_BASE_DIR.'org/puremvc/php/patterns/facade/',
            PMVC_BASE_DIR.'org/puremvc/php/interfaces/',
            PMVC_BASE_DIR.'org/puremvc/php/core/',
            PMVC_BASE_DIR.'org/puremvc/php/patterns/',
            PMVC_BASE_DIR.'org/puremvc/php/patterns/command/',
            PMVC_BASE_DIR.'org/puremvc/php/patterns/mediator/',
            PMVC_BASE_DIR.'org/puremvc/php/patterns/observer/',
            PMVC_BASE_DIR.'org/puremvc/php/patterns/proxy/' );
        $classPaths = array_merge( explode( PATH_SEPARATOR,
get_include_path() ), $_basePaths );
        foreach( $classPaths as $classPath )
        {
            $path = $classPath.$class.EXT;
            if( file_exists( $path ) )
            {
                require_once $path;
                return;
            }
        }
        throw new \Exception( 'Unable to find class '.$class.' in '.
            implode( PATH_SEPARATOR, $classPaths ) );
    }
}
