Portable Peer Guardian 2

I know someone has mentioned Peer Guardian before, and I just wanted to request it myself. I'm new to the forums but not to this site, and I love the portable apps. This is my home page, and my 1 gig goes with me everywhere. I just came across this program and noticed that it was open source, so I figured I'd throw it out there.

Here's a link if you're willing to check it out:

Essentially it's an IP blocker, designed to protect your privacy during Peer to Peer transfers. It was not developed for illegal activity, just to protect privacy. Anyways, let me know what you think.
