That old latching connector could still leave it with
a height problem for slick designs.

The cheapest mini-HDMI connector I found was advertised
as $0.10 - $0.20 for MOQ of 3000.
The cheapest magnetics I found was about $1.

Mixing HDMI and ethernet signals could be fatal to HDMI
though :( Any leaking mains or lightening strike entering
the cable also fatal to HDMI, while well built ethernet could survive.
