Yeh, just playing with Dongsheng's plugin now.
Well, I figured it'd be something you guys would be tracking. It'd be pretty big for Moodle to be able to use a generic Content Management System as a repository. Obviously CMIS is pretty new and it remains to be seen how "good" a standard it will be. The workflow and search capability of something like Alfresco would offer huge value to Moodle.
To be honest, I don't think it'll be at the top of their priorities ;)
