This is pretty good, but it seems to loose much meaning for me with
several equal servers,
ftp1.us.debian.org 111 ms 16 hops 91% ok (31/34)
llug.sep.bnl.gov 83 ms 15 hops 100% ok (110/110)
ftp.debian.org 80 ms 19 hops 93% ok (40/43)
ftp.cdrom.com 87 ms 13 hops 92% ok (39/42)

I'm sitting on a high speed lan conection (ie I get ~100k/s from llug)
Presumably this program pushes the network a bit hard and that is why
there is packet loss a straight ping to any of these sites will get 0%
loss.
My question is how can we build a single weighted score for each site? Let
the user pick one of the top two or so. But how do you weight?
Someone should definately work on this - I can make use if in APT in a big
way.
