Y'all remember DirectConnect? Kazaa? WASTE? Restroshare? You know, software where you could offer your entire media collection for share and people could browse and download as they liked?
What's the modern version of that, which
a) works, stably; and
b) is cross-platform at least to Linux and Windows?
