On behalf of every network operator on the planet, I would like to take 
this opportunity to encourage every person who implements a traceroute or 
traceroute like program to ALWAYS DISPLAY THE SOURCE ADDRESS IN THE OUTPUT 
OF THE PROGRAM!@#$%^&

Very few things in life suck more than asymmetric paths + wannabe network 
engineers armed with a noc phone number list and traceroute, mtr, or those 
wonderful visual traceroute programs that they insist on taking 6MB bmp 
screenshots of and sticking into word documents so they can email that as 
an attachment.
