That is correct, but anyone that knows my IP when I download something don't know the status of my download. My client could be lying about the pieces I have and the progress I do with the download. With Rapidshare it would only take one call to a judge and get a full list of all the completed and confirmed downloads I've made from Rapidshare. With Rapidshare there's also money involved.
