To use bittorrent, your machine has to listen, and otherwise be somehow reachable. In many cases, it's not a given, and sometimes not even desirable. It sticks out.

I think a variant of bittorrent which may be successful in corporate and generally non-geek environments should have the following qualities:

  - Work via WebSockets.
  - Run in browser, no installation. 
  - Have no rebel reputation. 

It's so obvious that it must have been implemented, likely multiple times. It would not be well-known because the very purpose of such an implementation would be to not draw attention.
