Does anyone know ANY application / patch / setting for Windows2000 to temorarily set an ADSL connection to transfer data (packets) to be that of a traditional 56K modem for testing purposes?

Have looked around everywhere on ADSL forums, providers etc etc and can't find any info on this at all! You can do this on traditional internal 56K Modems through the provided settings in the OS, but there's no equivalent for USB ADSL modems i don't think???

Basically i want to test some streaming media as a 56K user would see it, as ADSL is too fast to get an idea of what the end-user experiences and can be an optimizing nightmare sometimes!

Any ideas anyone?
