Peering Table Question

I apologize if this question is not relevant to your discussions, but Susan Harris, e-mail address srh@merit.edu, suggested that I ask it here... The peering table that appears on the London Internet Exchange web site www.linx.net/peering.html...... is this something that can be generated for different peering locations? Also with this information would it be possible to create a table that lists companies and the cities that they are peering in? Any insight would be of great help to me thank you. Once again any advice on how or where to obtain this info would be of great benefit to me. Thanks Jeff Lentz
