Can a new feature be created that limits the total percentage of a single file that is uploaded per user?

Lime Wire sets the bandwidth percentage and maximum uploads per person.

Lime Wire needs to limit the percentage of a file, per user that is downloading.

For example, if someone is downloading a file from me, I should be able to set the maximum percentage of that file, let's say 98 percent.

The user who is downloading from me and doesn't get the complete file would have to download the remaining 2 percent from someone else.

This new option would look like....

Tools -> Options -> Uploads -> Upload percentage -> 1% - 99%

Does this make sense?
