[Ubuntu] Media Center

This weekend, we build a media center to share a 500Go disk on the network (+150Go internal drive), using Ubuntu 7.10 and various open-source software.
Here is a list of them, and some links to ease their uses.

• Wordpress: to keep information about different login/password, configuration and link to each tool.
• Torrentflux: a php bittorrent client, so anybody on the network can add torrent in it, and we can easily control the bandwith consumption.
  • Recommanded settings
  • Fix for mininova search engine
  • ‘Start/stop all downloads‘ hack
• MythTv: with all our media library in one place, anybody on the network can launch MythTv and access categorised movies/music
• Network File System

Any advice, tools to add to this configuration? Might be really great to use the NFS as a TimeMachine, and easily back all our important data this way.
