Internet's resistance to measurement
                
many would benefit
vendors, users, researchers, ISPs
          
ISPs would bear cost   
multiple media: atm, pos, dwdm, mpls
logistics/management  
privacy implications
analysis/research obsolete after (before) done
                
   ........how to justify/accomplish measurement?
              (when market forces are torqued)

alternatives:
 1) tools that positively affect an ISP's balance sheet
 2) regulatory intervention
