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

The academic folks have bits and pieces from various

A number of the intrusdion detection/anti-DDOS vendors
may have probes located where they can collect some of this

the exchange point operators could assist.
