Must say that is a pretty cleaver idea. Well worth investigating and testing out. Then on the MT you just look to see if Ethernet link is up or down (ie relay is closed or open).

You need a $1.30 relay from Radio Shack. The relay connects to the AC and is "closed" when the AC is "high" (i.e. there is contact when the power is on). Then you wire it right into the Ethernet port of your RB, creating a "loopback" There's no need for switches, routers, Bullets, or any other piece of equipment.
