I would tone it down a little here since it is NOT a proven fact that the
bottleneck has to be an XCP router. But there is empirical evidence for
that. Also we are necessarily building a tool just for file transfer. Based
on these arguments, I would change the text as follows (it is just my input
-- you can change it):
There exists empirical evidence \cite{zhang-2004-xcp} that XCP is not
effective if the bottleneck router does not support it. The issue of
incremental XCP deployment is still open \cite{falk-xcp-00}. As the IETF
work on the XCP specification is still in its early stages and most routers
in the field currently do not support XCP, XCP, while an excellent
congestion control scheme, does not appear to be immediately useful to our
target community.
