the bottom line is, when you're on the outside looking in, there's only so 
much you're going to be able to see or analyze on someone else's network. 
everyone needs tools like this, and would use them.  trouble is, it's a 
hard problem to solve and design tools for.  many groups have formed to 
discuss "standard metrics" with respect to IP backbones.  i'm not sure 
there's ever been much concensus from them.

see www.caida.org.  just poke around, lots of data on the order of what i 
think you're looking for.  however, they usually anonymize (is that a 
word?) the data to be politically correct and protect themselves legally.

some folks at caimis.com (acquired by ixia) were doing some really 
interesting development of tools for routing performance metrics. 
www.ixiacom.com.

if you want to participate in standards for this kind of thing, go peruse 
www.ietf.org and look for the performance metrics working groups and netops 
groups.
