I hav asked this question before, on serverfault, but have been unable to get a clear answer or spammy ones.

A client runs a website with limited bandwidth per month (10gb) but wants his users to be able to download hq videos.

Now if he would rent hosting space on amazon, for example, the downloads would still go through his website right? So would this then still eat his bandwidth then, or not?

It there a way to circumvent this? How do you do this, if you have limited bandwidth?

If you are kind enough to answer, please don't spam me with what is good and not good hosting, I already know.
