So in smart-TV controller use case with streaming capability case you
would need the card to be plugged in at both ends to the TV? Both
plugged in as an PCMCIA-like card and with an HDMI cable going to the
same TV? I don't think that will be accepted as a vialble solution.

The smart-TV use case needs HDMI (or something else HDCP capable), power
and probably USB connected to the TV set. HDMI for deliviring the
picture stream for display on the TV, power for powering the EOMA card,
and USB for whatever custom control signals needed that do not fit in
the HDMI control channels.

Sure. Not saying these shuold be in first version. Only where I see
those things fit on cards having them.

plastic where? Isn't the PCMCIA card shield metal all around on the
internal edges (well not on the internal connector edge, but that's all
populated by the connector, can't fit an SD card there)

If we are to place anything on an internal edge then the PCMCIA metal
shield needs custom work (a hole cut at the edge) as it's metal all
around. 

Haven't paid attention to case discussions yet.

For a nice easily accessible extension connector withut having to tear
off the metal shield yes. But that's all optional. It's fine to simply
have two versions, one with PCMCIA shield and no extension connector,
and one bare board without shield but with extension connector. Same PCB
works in both, just different assembly.
