P2P Doesn't *HAVE* to share (Score 1)

Frostwire (a free fork of Limewire without the DRMA crap) and mIRC are two programs that I know of that the user doesn't specifically *HAVE* to share files. If one sets up Frostwire correctly, it will neither share downloads, nor anything else. By default, though, FW does share all files downloaded by the user until he/she moves them out of the incoming directory.

With mIRC, the process is rather detailed, and not very n00b friendly. There are several helper programs, (such as OmenServe's Addons (AutoGet specifically. A GUI interface for your mIRC downloading needs.))

I do share over 2,000 files, but they are all 100% legal, public-domain .MP3 files. I have the almost the entire collection from OverClocked Remix that I use to "pad my stats" if you will. Though, I don't know if "padding" is the right term, since that's the only thing that I allow to go out from my system.
