I'd like to understand what is using all this bandwidth.  He was 
running torrents for a while but I believe he stopped months ago.  He 
talks to friends on Skype.  He plays a couple of online games which 
occasionally have enormous updates.  Some YouTube.  Lots of Facebook 
and other lower-bandwidth stuff.  It seems that he is going through 
40-70 GB per month by himself and I really don't understand what he's 
doing that is consuming all that data.

BTW, with my D-Link router, I think I can limit his network use to 
certain times of the day (and block specific web sites) but I don't 
think I can "cap" his bandwidth.
