This would truly be a great thing. I've been trying for years, and it's really kind of painful, even with some good working knowledge of network infrastructure.

Here are some decent software I use. Not all OSS, unfortunately, but they still let me posses my data.

- Subsonic (music) http://subsonic.org/

- OwnCloud (files) https://owncloud.org/

- BitSync (files, begrudgingly) http://www.bittorrent.com/

- Apple Server (webserver/VPN/SSH)

- Lots of nice blog/web serving software once you get the web stack up and running.

Email's rough. Photos are also rough between either thumbnailing/cacheing all your photos, or multi-second processing.
