I use unraid and it hosts all my media files. It would be cool to be able to have a docker container that has a read only share and I could assign a wifi adapter to it to stick in the window/where ever.

Moving to a rural area in the next few months and it would be cool to have a streaming media server running off of it for people to use that don't have a net connection.

Plugins like a sip, irc, email, torrent server would be cool also. Would love to see more decentralized ways to share stuff with people in a area.
