We started by using the NAT peer to peer, but it just wasn't stable enough. On some systems it worked great, but others had too many problems. So we went to a proxy system. I didn't use the raknet system but wrote it myself because it was easier at that point and had less code changes. We are VERY HAPPY with RakNet and I really hope that we make enough to pay Jenkins for their great software. It is a great program that allows an Indie such as us free use of your code. It will be our pleasure to be able to pay you, so wish us luck!
