Never needed to or even thought about it. uTorrent never gave me any issues and was super lightweight. Additionally, there was a fansubbed anime site I was a member of for a long time that had a limited whitelist of p2p clients last they would allow their trackers to function on. uT 2.2.1 was one of those.
That pc seldom gets used anymore nowadays anyway, as my main pc is running OpenSuse and ktorrent does all I need it to.
