Amigamance,
I know that sometimes is convenient degrade download speed to salve bandwidth for another tasks like browsing
but that is concerned to every task or program...because if the program that you are using use the full bandwidth and that program haven't settings you can't do anything
I think you are looking for a patch or program to regulate the bandwidth of any task....but I think that still not exists....
or maybe impossible to do
be the first and code one
