Does anyone know if the "Message from Earth"[1] sent towards Gliese 581c can conceivably be received at this new planet?

If there is intelligent life in that system capable of detecting and transmitting signals of that form (NOT assuming that by any stretch), a response is due in ~2049.

While we're on that topic, wouldn't such a hypothetical civilization already have discovered other electromagnetic radiation from our system by now? Or does it have to be a focused high-power signal as this one?
