The ideal system will be open-source, and it can deliver photos, streaming audio and video online. It also requires authentication module for password/login. I know there are Avalon project and Fedora. Besides these, any other recommendations? If you deliver photos, Video and audio with any open source system, I would love to hear your suggestions. Thanks, Yan
