Relay Mode & Control over EzWifibroadcast

[Lootgeier]

Would it be possible to have the receiver pi on my roof for example and then stream over LAN or normal Wifi to a second Pi that could sit in another room so you could watch the stream from home without needing to extend the antenna cable 20m?
Also if it would be possible to stream like SBUS signal back to the RC Model you could control with the Taranis from inside your car/house and still have great range. Just for winter or even hot summer when you dont want to stay in the cold while driving your RC Car around the fields.
