That 250k should be split over all the cvsup servers in the US, not just pointing at one. That works out to about 15k if you say 16 cvsup servers to pick from == about 2 years for every machine to cvsup just once, at a rate of 1/hour. -------signature file------- PGP Key Fingerprint: 446B 7718 B219 9F1E 43DD 8E4A 6BE9 D739 CCC5 7FD7 "I don't think [Linux] will be very successful in the long run."
