[Zope] Upload to Filesystem

Hello, I am currently in the process of deciding whether to use Zope or PHP for a web based editing system. While browsing over the Zope email archive I saw some announcements/request of a filesystem based upload system, but not really any replies. What is a good way to upload Files via a web interface to the Zope machine's (not necessarily accessible from Zope after upload) filesystem. We want to serve Real Audio files from this box, too, but i don't think storing hundreds of Real Audio Files in the object store is a good option (and wouldn't work anyway, because the RA Server needs physical access to the RA files). Any possible solutions? thanks Oliver
