We don't currently have any plans to implement either, but you're free to do so yourself. The wifi backpack allows creating arbitrary TCP and UDP connections, so it should be able to do MQTT. We use the Arduino software as-is, so any existing MQTT-for-Arduino implementations should be usable (with some adaption, perhaps).
As for Skynet - not sure how that would work. It seems they have a few protocols you could implement on the scout side, which should be possible as well.
