PHP admin screens for Flex objects

I am creating Flex application that will call PHP via Zend_Amf.
It's basically CRUD operations with file uploads sometimes.

This will require to create admin screens for PHP side (for editing various records on server) automatically, using scuffolding.

It seems that CakePHP would do well at generating admin screens.

How well does CakePHP handle AMF, how professionally?
In case CakePHP/plugins doesn't handle AMF well, is it possible to replace CakePHP models with custom models which use Zend_Amf class from Zend Framework?

My most concern is the ability of PHP-based AFM handler to handle file uploads from Flex to PHP.
