  • Queues torrents for file check, instead of checking all of them in parallel.
  • Uses separate threads for checking files and for main downloader, with a fool-proof
    thread-safe library interface. (i.e. There’s no way for the user to cause a deadlock).
  • Can limit the upload and download bandwidth usage and the maximum number of unchoked peers.
  • Piece-wise, unordered, file allocation
  • Implements fair trade.
  • User settable trade-ratio, must at least be 1:1, but one can choose
    to trade 1 for 2 or any other ratio that isn’t unfair to the other party. (i.e. real tit for tat)

    separate fast-resume file.

  • Supports files > 2 gigabytes.
