I'm not sure how you can set a limit for a single application and any of its 
child processes with ulimit.  However, Control Groups (cgroups) can do this

Also, from what I recall at least some torrent applications can limit the 
amount of uploading connections and/or throughput - but I haven't used any for 
years now.
