here is a bit more trivia for those interested: the 4 main 'seeds' that came up were each running with 100mbps open uplinks. Atleast one person in the early stages was running at 200 odd mbps.

That's dedication... I decap my bt-client after work hours (from 1700hrs to 0700 weekdays, and full speed continuesly over the weekends). I wonder if the ridiculously high 40k-share ratio Azureus reports here has something to do with this. Hmm...

geez, makes me wonder if I should even bother to leave mine running with a 50kbyte/sec uplink ca (thats about 500kbps)... if I raise the cap much higher, it seriously throttles my home network (6Mbps in, 700k out)... I know, I know, I should implement some form of QoS or packet prioritization at my firewall.

If you can - you should. The costs of running those torrents at 100mbps is way too high to run over any sustained period of time ( and they are all offline now ). So once the first rush has spread out - the whole user experience is totally driven by the other users part of the deluge.
Normally, I'd keep 1 machine running from within .centos.org to make sure there was always atleast 1 seed for each of the torrents. And that machine runs only at 10mbps, for all the torrents and is also a part of other services within centos.org

Aren't these speeds a relative notion, ie. dependent on where you are as a peer?
I mean, I have a 100Mbps link to my local LAN, which is connected via a 2Gbps optical cables to my national center, which in turn has several uplinks of various bandwidth (from 32Mbps to 10Gbps) connected to surrounding countries. From there on I don't know. So how can I be sure that for example someone on the other side of the planet can utilize my whole bandwidth?
Of course, we can initiate some peer-to-peer data transfer and measure the actual speed, but isn't the terminology "100Mbps to outside world" a little bit undefined in general? Because not all parts of "outside world" may always have greater bandwidth than my uplink?
Is there maybe some web site with a planet-wide topology of the internet, along with actual bandwidths of all the links, so one can estimate the transfer speed between two arbitrary points on the globe?
FWIW, tommorow I'll use torrent to download the dvd iso's for CentOS 5.3 (32bit and 64bit archs), and I can leave them seeded 24/7 for an undefinite time in the future, cca 3 years at least, or maybe untill 5.4 appears. If anyone can pull 100Mbps from me, I'll be glad to help the community. It's only that I am not so sure that it is well defined to say "I have an 100Mbps uplink". Uplink to my nearest neighbor, yes, but further than that...

The ISP's that sell you your uplink are supposed to take care of actually having sufficient bandwidth to their peers.

yes, which is why I said all these machines were locaed inside hosting DC's - which normally have good connectivity. One on the East coast US, one on the West Coast, one in Germany, one in London and the rest coming on at diff places.
What makes a major difference however is when there are a lot of people, even with lesser speeds, seeding at the same time.

Thinking of analogies, if one person throws a small stone at you, maybe you get a small bruise at worst. If a thousand do it at the same time you *die*, likely.
That is to say, thousands throwing packets your way all at once tend to negate a single-point bottleneck existing between you and any specific source off your ISPs network, if they tend to come from all different directions (different remote networks). 'Course if you live on a nasty cable provider (we'll leave them unnamed here) who feels it right to throttle you based on various usage statistics, you may only get hit by a few stones at once.

But with bittorrent, one person doesn't use all of your bandwidth. Hundreds of users are each using a small percentage of it. So if you have 100 peers accessing 100 different slices of the torrent at 1 mb each, there goes the whole 100 mb.

Every little stream helps when using bittorrent, even at 50kbps upstream, so keep seeding! ;-)
I think my ISP at home has done something with regard to p2p. I can't seed at home anymore for some reason... 8-/
