What does the contract specify?

With jitter being the variance in latency from packet to packet?

Here's what I see on a Covad DSL link:

lex:~# foreach host (mit.edu bu.edu www.harvard.edu brandies.edu neu.edu 
www.cnet.com www.google.com)
foreach? ping -qc 5 $host 
           foreach? end
PING mit.edu (18.7.22.69): 56 data bytes

Average seems to be around 35 ms.
