 have any effect on measurement results, because all requests and responses
 traverse the Tor network.
 
+Reasons for \emph{not} separating client and server are:
+\begin{itemize}
+\item it's easier to deploy client and server together than deploying them
+separately and configuring the client to use the server;
+\item measurement results can easily contain client and server timestamps
+of a measurement;
+\item assuming the host has sufficient free bandwidth capacity, measurement
+results shouldn't be affected by client and server running on the same

+\item it's not unusual to deploy client and server talking over Tor in a
+single tool: think of how a tor relay does bandwidth self-tests to itself.

+What's not easily possible with this approach is to configure client and
