+Several other factors complicate our analysis, which we leave for future
 work.

-First, companies like Akamai provide web hosting spread around the globe to
-be close to any given user. They therefore present a real problem for
-this analysis. Because the exit node will choose a nearby Akamai
-server, Alice can no longer use the scheme in Section~\ref{sec:mix_aspath}
-to estimate the AS-level path between the exit node and her destination.
-Also, Akamai itself becomes a powerful global adversary with respect
-to certain popular websites.

-Second,
-how sensitive is our independence metric to addition or removal of a
-few nodes in the topology? It seems quite insensitive, but more research
-remains.

-Third,
-our choice of popular locations for initiator and responder were all
-inside the United States. Does the analysis change for foreign users?

+Finally,
 for Alice to use this approach, she must periodically fetch routing tables
 and estimate the Internet's topology---which requires lots of computation
 and bandwidth. We must devise a way to condense this information;
