Best bet is to take the raw video and run it through gstreamer. You should be able to setup a pipeline which displays the raw video locally while sending a compressed stream to the network. I'd bet that Nvidia has gstreamer modules which make use of their compression HW, so it might be possible. To be honest though, that's a lot of data, so I don't know how well dual 4k would work. You can always scale it down in gstreamer before you send it to the compression module.
You'll probably want to use the CSI-2 interfaces to connect the cameras, but that depends. CSI-2 was developed for cell phones and is hard to run over long distances. It's optimized for low-power and designed for very short interconnects. We had a ton of problems using it at the last company I worked for. I really wish there was a competing standard for embedded cameras.
