"No. ADSL uses different frequencies for upload and download. If you were uploading a file at your maximum capacity, not one bit of your available download bandwidth would be used. Open it us so others can get a better download speed."

This is not true. The main problem with, for example, a 512/64 ADSL connection, is that when you are uploading you almost can't download because the acknowledgement packeged can't be uploaded as fast as they should be. This is expecially a problem with the dutch ADSL mxstream. So when I am uploading my download speed decreases considerably. So, you are true if you're speaking at the lowest hardware levels of the ADSL technolegy, but at the ATM and TCP/IP level there is a lot needed overhead for uploading files. Since the upload speed isn't that high your download speed is suffering very much when you are uploading a file.
