Tired of paying Microsoft's fee for playing on XBL? Don't use the other features like Netflix, Zunes, etc? Well, there is a free version out there for people to use. It is called XBConnect. What it does is trick your xbox into thinking you are on a LAN network. Instead, it connects you to millions of people around the world!
It now supports Halo Reach!
Check it out: xbconnect.com
P.S. Of course, this is also another solution for those of us who somehow, accidentally, got banned.
