Any media players with content focus for children (preferably with cableCARD support)
I like the new Kids area on Netflix (when I tried it with a desktop web browser).
I thought it would be nice if there was an media playback STB/dongle (attached to TV) that has menus/Theme/selections/channels/views/ meant for children. If it could play games, that would be nice too.
Also, if the device can detect and take advantage of cableCARDs for Live TV (either over LAN or builtin).
