Not sure I have seen this DLS reports speedtest mentioned before.
It produces an interesting take on displaying the data.
The results pretty much matched those with speedtest and thinkbroadband, so its getting accurate results.

Here are a couple of mine (my sky sr102 connection speed is 23.2/1.2mbps).
