no, you should be able to detect network speed, because tcp uses smart end points, and dumb relays.
basically, if the network is "slow", packets will be dropped before they reach the other end, and have to be resent. this should manifest it self in node as write()=== false on your HttpResponse object, and a 'drain' event it is ready again. if you stop writing to a stream when it asks, then this should theoretically be something like the network speed. of course, you could have the client stream something back, too. here are two modules for measuring the throughput of streams, https://github.com/fent/node-streamspeed https://github.com/dominictarr/probe-stream keep in mind that it may not be accurate if you are piping to the network with a stream that doesn't respect pause. it's probably best to have the detector on the receiving end.
