There just isn't useful public data out there that is extensive enough, relevant, or complete. There are lists of "top 50 web sites in the UK", "top 10 most popular sites", and "15 top financial sites", and such, but I couldn't find anything useful that was based on true traffic analysis, or wasn't skewed by incomplete views.
Of course, many commercial providers consider this highly confidential data and don't share it, assuming they reliably collect it at all. The last commercial provider I saw with any public traffic analysis was ANS. The academic folks have bits and pieces from various networks, but as I suspect you know, it comes and goes.
Netflow data from various sources is proving to be the most useful, but I need more views. If anyone has any [Netflow or Netflow-like] top-speaker information that they would be willing to share, I'd very much appreciate it-- please drop me a note offline.
A number of the intrusdion detection/anti-DDOS vendors may have probes located where they can collect some of this information. And depending on the permision of the customers' the exchange point operators could assist.
