clarify if this shares files

[anarcat]

it is unclear from the description if this tool actually starts sharing files once they are downloaded locally. it would be great to have more information about how this is implemented, basically - which library is running in the back, does it stream files and generally how it works and so on.

To answer your questions:

1. Yes, it shares as long as it's mounted.
2. It uses libtorrent (http://www.libtorrent.org/)
3. BTFS maintains a sliding window of pieces (https://en.wikipedia.org/wiki/Sliding_window_protocol). When a program reads a file, this window will be moved to that offset. The window will be moved forward when pieces finish.
