So, as you probably know, we do a lot of iSight-enabled iChat AV sessions with Grandma. On our end, we have the iSight attached to an iBook on a wireless network, so we just wander around after the boy (nee Grandson) and Grandma watches. He can go to the basement, to the bedroom, or even outside, and we can follow.
And yet, the iBook is unwieldy. In a moment of frustration as I shifted the a-bit-more-than-warm iBook around on my knee while trying to keep the boy in frame, it occurred to me… this would be better if it were a video camera.
The iSight Express would be an iSight camera, a WiFi connection, and two LCD panels back to back. It is okay if they are small, maybe 320 x 240. You point the camera at your subject, and you see them in the LCD facing you. They, in turn, see the other end of the conversation in the LCD facing them. All of this gets sent via WiFi to your computer, which is managing the connection.
The iSight Extreme is similar, except that it is a full client on the network, negotiating its own IP address, and making its own connections, no computer needed.
If Apple isn’t working on this yet, they should be.
