Traceroutes (any transport) can go anyplace. Of all the measurement 
classes, only HTTP measurements must go to anchors.

So yeah, breaking out data-plane deltas between endpoints is feasible.

Emile's IXP-country-jedi stuff can pull together traceroute data and 
help visualise spatially the differences between v4 and v6 paths;
