If you visit #fedora they tell that its near as damnit evil to obtain it this way, but the way I look at it is it should help give the main servers less of a hammering during the mad scramble to download a new release from one of the big distros.
So far I've seeded 1.5GB, I think thats a good thing, others may not agree though.
You also run the risk of downloading dodgy iso's of course.
