I know of people in different areas which have a higher upload speed, almost 3x as fast. So, it's possible to have higher speeds in DSL lines - just not where I'm at. As for my DSL line, I like the consistent speeds it gives me. (I think that a cable connection couldn't give me that due to it's nature)

However, I think the best solution would be to have the client respect the settings that the users sets. For instance, If I set it to use a max of X KB/s, it should. I could then limit the bandwidth up to have better download speeds. (Right?)
