In one of my current projects, I came across a scenario to play a video based on the users downloading bandwidth. The detection should be done with javascript. There is a technique, to load an image of known size and calculating the bandwidth on basis of time taken to load that image. Though this technique is not 100% reliable, this will give an approximate estimate of bandwidth.
