Lexip; said:would be a lot easier to use an existing protocol. MSN, AIM, Yahoo, etc. That way you can chat to people on not just wii's, but whatever supports that protocol. I don't really see the point in having it unless yout could run it on top of another app.
...You would be surprised at the ammount of time some of us spend on messenger alone. Shoot, I'd rather be using messenger on my Wii which will max at 24 watts then on my PC which could max out at 400 watts. Thats a decent ammout of electricity and money saved.
