Yeah, to give you a sense of the chances, I run OS 10.2.6. More or less 24/7 for the past say, month, i've been running Limewire. I keep five slots open, i'd say on average at least three are filled all the time. So, let's say, over the past month, perhaps thousands of files have been uploaded. I think that's a fair estimate. I've never had a problem.
