I know Comcast is going to introduce an Amazon Fire like TV Stick. In which their modem has the MoCA and tuner built-in to it. Some of the modems that they are installing already have MoCA built in. So if the modem has MoCA printed on it, usually around the coax input. Then it has MoCA.

This stick is going to connect to the TV via wifi, and presumably a power source and connect to the network via their wifi modem with MoCA.
