#Copyparty, the FLOSS file server you've never heard about.
16 minutes of very dense video that had me smiling throughout. Looks like a great tool for sharing files with friends, family, or thousands of random hackers on a field in the Netherlands.
I could list some of the features, but that would probably spoil the experience. Take the number of boosts of this post as an indication of whether it's worth a watch.
Or, if you really hate video: https://github.com/9001/copyparty/
