// We need a new repository
class DropboxRepository extends Repository
{
    public $code = 'db';

    public function getZipUrl()
    {
        // Somehow fetch URL to zipball from Dropbox ...
        
        // ... and return it
    }
}

// Bind the repository to the container
// NOTE: This is actually not neccessary, since WP Pusher can automatically
// compose dependecies by using PHP's reflection API. This would only be neccessary
// if you wanted to bind DropboxRepository to an interface implementation.
add_action('wppusher_register_dependency', function(Pusher $pusher) {
    $pusher->bind('DropboxRepository', 'DropboxRepository');
});

// Then we need to overwrite the RepositoryFactory (this is just
// an example and should probably not be done unless it's a private
// plugin, since it could cause conflicts with other similar implementations)
// so WP Pusher knows how to create a Dropbox repository:
class MyOwnRepositoryFactory
{
    public function build($type, $handle)
    {
        if ($type === 'db') {
            return new DropboxRepository($handle);
        }
        
        return parent::build($type, $handle);
    }
}

// We can then overwrite the RepositoryFactory in the container,
// so that an instance of MyOwnRepositoryFactory is returned
// whenever someone needs a repository factory:
add_action('wppusher_register_dependency', function(Pusher $pusher) {
    $pusher->bind('RepositoryFactory', 'MyOwnRepositoryFactory');
});

// Now, you'd only need a few adjustments to the UI, to allow users to
// select Dropbox as a repository!
