I think it would be awesome if you showed us some ideas for using the cheap wireless module nRF24L01. They are cheap and that makes it perfect for hobbyists they can be found for less than $5 a pair whereas XBEE kits are closer to $100 . This could be a good first project for those who want to add wireless sensor grids or control an arduino remotely or possibly control servos and stepper motors. The info out there on sending logic wirelessly can get a little confusing. I hope you'll consider this. Good luck on the dreamcast part 3! Thanks
