Aren't we missing something obvious here? Shouldn't we be using some sort of distributed technology like BitTorrent?
That's been asked and answered... Bittorrent is meant to optimize download of large files when there are many peers.
Not really, the protocol is tunable to scales down too (just use small chunks for the torrents).
Sure there will be more overhead BW-wise because the aggregated BW is always more than the one you get using a central point of distribution and the overhead gets bigger when the files' sizes go down.
But this isn't the point, the point is : you get rid of the central distribution point(s) bottleneck. The aggregated BW is distributed on as many links as freshclam instances... You may want to have more than one tracker though with DNS views to redirect people to a local tracker, I don't think a tracker scales well beyond 100000 clients today (you could use the multi-tracker extensions too).
We could effect the many peers, but the size of the files involved are often finished downloading before a torrent file is downloaded parsed, and attempted (there are always unreachable / not responding hosts / slow hosts / bad routes etc.)
a summarization of my understanding anyways.

In fact the main obstacle is the firewall setup needed for such a scheme for each client. One possibility would be to provide 2 distributions paths : the current one, DNS-enhanced for administrators worrying about a new port open, a parallel one for people looking for near zero-delay, using the bittorrent protocol with adequate sigs for torrent as I described earlier on this list.
Anybody with some time to spare ?
