Bug Description

We want to be able to use bittorrent to download files. This will be very important for the player, but also for the editor.

It seems the python-bittorrent library would be a good bet as it's in main and is quite small:

http://packages.ubuntu.com/python-bittorrent

This will be built on top of FileStore, which probably needs a few API changes to support this elegantly (I'll file a bug for this). Right now we just need the downloader as a rather independent component, but later we will integrate the bittorrent downloader as one the the options dmedia-service will use for queued downloads.

Another thought - AFAIK, by default bittorrent will download chunks from random positions in the file, but this doesn't work nice for progressive download (watching as you download). Not sure if python-bittorent API makes it easy to control the order the chunks are downloaded, but that would be a totally bonus.

Lots of good information here:
