How can you tell which isps use traffic shaping?

I know that bt now use traffic shaping, so does this mean any isps using certain ipstream connections will automatically be traffic shaped also?

On the thinkbroadband website I have been looking at isps, and it says the wholesale product which every isp uses such as IPStream Max and premium, which products are traffic shaped?

Ah, is there a list of isps that do use traffic shaping? I remember when we had bt, we got 30Kb/s in the daytime just trying to download a file, so while other people are using p2p in combination with vpn and encryption, us normal users were crippled.
