at home I have my media and files stored on a hacked pogoplug with a large hard drive. media (music, videos, photos) for access across the lan or internet:

it runs debian, with mediatomb for upnp streaming on the lan, ampache for music streaming across the internet

It also has nfs and samba file sharing within the lan, and ajaxplorer as a web based file explorer. Oh and transmission and a calibre ebook server is on there as well.

the idea is that i can acess the data from any of my devices, but mostly the n900 and N810.
