That's old and it's dependencies doesn't work with iOS 5 (at least for me). I've been happy since I met itransmission-cli (for some reasons, itransmission 2 can't bind to its webpage...). I can grant you it's the true equivalent of the Mac OSX client in terms of speed and reliability.
Just rebember to pause the seeding as otherwise the daemun will continue to work, even with the blocked screen!
