I remember seeing one of these as an add on the Utorrent but couldn't figure out how to set it up and test it.
Is there any mileage in using the utorrent ip filter if Block List Mgr is being used (in Peer Guardian 2) ? - http://forums.afterdawn.com/thread_view.cfm/631385#3821281 ..or (if something like BLM is being used) maybe the ip filter is useful just for rooting out fake peers then ? edit- From what little i've read it would seem that BLM is sufficient, as is PG2, not sure the ip filter is needed over and above BLM/PG2..
Before you go putting too much faith in these blocklist things read this.. http://dmca.cs.washington.edu/uwcse_dmca_tr.pdf Better to use a private tracker and heavyweight encryption to keep your isp out.
