Good point.  That could work.

Computers can and often do have multiple Ethernets.  Yes, they make
PCI cards that supply Ethernet ports.  You can even get PCI cards
with multiple Ethernet ports.  I've seen PCI cards with 4 ports.
Some mainboards have more than one Ethernet onboard.  They also make
USB-to-Ethernet adapters, so you can get an Ethernet port without
using up a PCI slot, assuming the computer already has USB.

You don't necessarily need a dedicated Ethernet to run this, even if
you are viewing HD video.  OTA HD mpeg2ts is approx 19 Mbps max.
That doesn't fit on 10 Mbps Ethernet, but is only about 20% of 100 Mbps
Ethernet, or 2% of Gigabit Ethernet.  This assumes that the decoding
happens at the terminal, not in the host computer.

So a computer with only 1 Ethernet could connect to a hub/switch/router
type box and the terminal can connect to some hub/switch/router type box.
The terminal is just another node on the network,  The terminal can talk
to any computer on the network you like.  No KVM switch needed.
