For me, the best feature this could have is online internet two-player support for original Intellivision games. They say it will be a feature for the new platform but I'm not expecting it for its intellivision emulator. That's something we can't do now.
I was actually pitching that to Keith Robinson before he died. It's Netrogames. My method is different. Assuming my theory is correct, it can do it with the original ROM without making any net code, so it will work with Data East, Hanna Barbara, Disney, etc. games. Also it SHOULD work with only 56kb/s because you have sub-8ms ping time. Visit http://www.netrogames.com for details.
