Both jigdo and bittorrent take the load off the servers but AFAIK you still 
have the total download to do yourself if you using bt.

So for me, on dialup bt is really out of the question. With bt there are 
other potential problems if you have to pay for upload. Here in dotAU our 
local PC magazine reported the story of a subscriber to Bigpond broadband, 
cable I think, who got a bill for $8,000 or $10,000 because she left a p2p 
link running unattended after the download was complete.

But jigdo for the NONUS iso requires only 40/1600 files to actually download 
with a starting point of _r1 iso and an uptodate system. The overhead for 
NONUS is about 28 megs.
