When I first looked into Bittorrent you could limit the amount of
bandwidth it used, but not the amount of data transferred. I guess by
limiting one you do have some element of control over the other, but not
a lot. Also, from my first experiments, until you've shared a decent
amount of files you don't get anywhere near the speed of download that
you get with a straight download of a half decent server. I think my
first attempt was with Debian, although I could be wrong. I set things
up to download an ISO of around the 600M ish mark and left it over
night. The initial speed estimated a download time of around 4 days, but
I assumed that this would improve as things progressed and I was sharing
out also. When I returned to it some 12 hours later it had downloaded
around 25M and had improved the estimate to about a day and a half. That
seemed to imply that you only managed to get a good download speed if
you left your connection open 24/7 for others to use, and after a few
days or weeks you would start to be seen as a good seed and hence get
improved download speeds.

I've just found that Opera seems to have a bittorrent client built in,
so I'm going to experiment by opening up the required port, although
it'll take a bit of configuration on my routers and firewalls to get it
through to me now - not such a simple network setup as I used to have.
