I have an idea about boosting one's downloading in a
swarm, and wish your kind evaluation and implementation.
Suppose I have several friends whose machines are often
idle when I want to download something via a torrent.
These friend machines have quite good broadband
connection speed with my machine. Because of some
agreement between us, they allow me to signal their
machines to join a torrent of my interest. So these
friend machines automatically join a torrent when I do.
But this alone may not help boost my own downloading
much. So, I would like the friend machines and my
machine to try download chunks different from that of
each other. As soon as these macihnes combined have all
the chunks, they can quit the torrent (doing so all of
a sudden can harm the rest of the swarm, so somebody
advised me that they should quit one by one in moderate
intervals), and transfer their chunks that I don't have
yet to my machine. Of course we assume that downloading
these chunks via the torrent is slower than via the
friends-to-me broadband connections.
So, can this friend-machines-assisted approach make my
downloading faster than my machine alone in the torrent
