Does µTorrent work on a 486 with Windows 95 and 14MiB of RAM?
DHT (Distributed Hash Table, technical explanation) is an addition to certain BitTorrent clients that allows them to work without a tracker. What this means is that your client will be able to find peers even when the tracker is down, or doesn’t even exist anymore. It allows the swarm to continue as normal without a tracker. You can also host torrents without a tracker. (see Does µTorrent support trackerless torrents?). µTorrent’s DHT implementation is the same as Mainline and BitComet’s, but unfortunately this is incompatible with Azureus’s implementation.
