I'd be surprised if this works for anything latency sensitive over anything more than a LAN.

Even just the time it takes speed of light between NY and LA (410^6m/310^8m/s=1/75s) is roughly how long a 60 fps frame is (1/60s). Add OS serializing the frame from the GPU onto the network card, network switching of those packets, and you're starting to really feel that latency.
