DHT = Distributed Hash Table, it is a feature of the BitTorrent protocol for decentralized torrents i.e. without a tracker.
With all the recent trouble from MegaUpload and all the other file hosting sites in mind: it might be worth considering to use trackerless torrent. We’d share the torrents amongst ourselves, but we’d have to keep them seeding.
Problem is of course that if someone from outside, who wants us down, logs all the IP adresses and collects them as evidence against us. That would be bad.
The main consense here is that all shared software—be it games, applications or other documents—are discontinued by the original distributor and therefor no longer available in the sense of “buyable”. I guess, with this in mind, we could establish a torrent network that exchanges all the good old stuff that is preserved here—without risking a lawsuit?
Just an idea.
