That's very sketchy ground. Distributing it is illegal. Your license probably also gives you the right to use the copy on the enclosed media, not to download and use a copy from the internet. Downloading it involves creating a copy of your own, which is probably also against the license. Obviously of course I'm sure you're also aware that bittorrent and lots of other P2P methods involve uploading as well as downloading.
Plus, I never trust that if I download software it won't have been messed up in some way or another.
