I don't want a software based solution that compresses my current display and streams it to a device on the local network. What I want is two HDMI dongles that literally function like wireless cables. Plug one dongle into one device. Plug the other dongle into the other device. The result should be exactly the same as if I had an actual HDMI cable. No software configuration. No wifi setup. Maybe a light on each device to indicate if the signal is strong enough and if they are connected to each other or not. It's not complicated. That's all I want. Someone, please make this! For that matter, there's a huge market for all sorts of dongles of this nature. Wireless audio cables that transmit digitally, for example. Basically, I want to just do away with wires and replace them with bi-directional dongles of some sort on each end.
