I've seen videos of the XFPS 3.0 and I'm impressed. However, I have a few questions to ask people who have one before I buy one myself.

1. Can you use the XFPS and have another player logged on a different controller and play at the same time?
2. Can it work on all games? For example, GTA, GoW, or even racing games?
3. I've heard of deadzone issues. I didn't notice anything that bad on video demos, but how has it been in real life?
4. Do you have to reset the keyboard mappings everytime you turn the 360 on?
5. I don't think you can, but just incase I'm wrong, can you be banned from XBL for using this?
