 distributed hash table (DHT) 라는 것이 2000년대 초반에 정부기관에서 펀드도 많이해주고 개발이 많이 됐었네요.

-----------------------

In 2001, four systems—CAN,^[3] Chord,^[4] Pastry, and Tapestry—ignited DHTs as a popular research topic. A project called the Infrastructure for Resilient Internet Systems (Iris) was funded by a $12 million grant from the US National Science Foundation in 2002.^[5] Researchers included Hari Balakrishnan and Scott Shenker.^[6] Outside academia, DHT technology has been adopted as a component of BitTorrent and in the Coral Content Distribution Network.

Streaming 지원은 은 2007년 부터 만들어졌다고 되어 있네요.

--------------

In general, BitTorrent's non-contiguous download methods have prevented it from supporting progressive download or "streaming playback". However, comments made by Bram Cohen in January 2007^[11] suggest that streaming torrent downloads will soon be commonplace and ad supported streaming^[12] appears to be the result of those comments. In January 2011 Cohen demonstrated an early version of BitTorrent streaming, saying the feature was projected to be available by summer 2011.^[13] As of 2013, this new BitTorrent streaming protocol is available for beta testing.^[14]

Podcast SW에서도 지원했었네요.

• Podcasting software is starting to integrate BitTorrent to help podcasters deal with the download demands of their MP3 "radio" programs. Specifically, Juice and Miro (formerly known as Democracy Player) support automatic processing of .torrent files from RSS feeds. Similarly, some BitTorrent clients, such as µTorrent, are able to process web feeds and automatically download content found within them.

블리자드가 게임 download를 위해서도 썼다니.

• Blizzard Entertainment uses BitTorrent (via a proprietary client called the "Blizzard Downloader") to distribute content and patches for Diablo III, StarCraft II and World of Warcraft, including the games themselves.^[36]

제가 알기로 사람들이 제일 많이 쓰는 bittorrent client가 uTorrent로 알고 있는데 최근버전에서 bitcoin을 mining하는 툴을 심었다고 합니다. Control panel에서 add or remove program에서 제거할수 있지만 파일이 그래도 남는다네요. 위치는 여기라는데, 제가 같은 버전을 쓰고 있어서 확인해보니 없습니다. 제가 제거한 기억은 없고 저한테만 설치안했을리 없으니 어디다 숨겨놨네요.

C:\ProgramData\EpicScale\0\

(It is possible to uninstall EpicScale through the control panel, but that does not properly remove the files from ProgramData\EpicScale.)

Also, several executable files (epicscale.exe and epicscale64.exe) as well as multiple .dll files were left in ProgramData\EpicScale and sub folders after uninstalling EpicScale through the control panel.

한국말고 뮤토렌트라 하기도 하고 유토렌트라 하기도 하지요. 처음에 시작은 정말 작고 빠른 프로그램으로 시작했는데 역시 수입이 없이 오래동안 유지보수까지 할수가 없지요. 광고도 넣고 Pro버전도 만들어 Pro버전을 하도록 유도하고 donation도 받고. 결국 마지막에 선택한 것이 비트코인이라도 벌어보자 하는것 같습니다. 이해는 하지만 충분히 설명하지 않은점이 괘씸하네요. 많은 사용자들이 이렇게 외치고 있네요.

GOOD BYE µTorrent.

다행히 바이러스도 아니고 spyware도 아닙니다. 영어로는 riskware라고 얘기하고 있네요.
