These folks have a LIN-like modem that provides serial communications over power lines...

Seems like a good fit for the Arduino.  Using just two wires it would be possible to provide electricity and communications for a few connected boards.

Thoughts?

seems interesting, but I cant figure out what exactly I would use it for. Maybe I dont completely get it.

care to describe a potential application?

I have seen similar application. Overhead DC crane intercoms. Crane to crane and crane to offices. In this case it is low quality audio.

Here's a simple one that popped up immediately: scoring a Pinewood Derby.

At the finish line, you set up 2 photo-interrupters on each lane, wired to an Arduino.  It can then both tell who came first, and how fast each was going, and relay that to the scoreboard system over a noise-tolerant 2-wire connection, instead of trying to connect all the individual sensor signals.  You could also put photo-interrupters at the starting line with another Arduino, and time the whole race (+- a little for communications latency).

Or make an Arduino-based outdoor weather station with only two wires going back to the indoor PC.

It's kind of like being able to design your own Dallas "1-wire" devices, but even better, because the power/data wire can be used to supply other devices like servos and relays.

Smart outdoor lighting.  We live on a few acres that border the National Forest Service.  Coyotes (and now mountain lions) occasionally poach a family pet.  I really don't want my dogs to be eaten.  I want motion sensors and lights far enough from the house to give us an early warning (think yards instead of feet).  Which means long wires.  If a single pair of wires can carry both power and communications, I can use basic outdoor lighting cable, the cable only has to pass through each node once, and the whole thing becomes a network.

Halloween.  Just imagine how simple setup would be for a yard display if only a single cable needs to be run through all the props and sensors?

Exactly.  All the LIN bus transceivers that I found include a built-in switching voltage regulator.  They're designed to work at car battery voltage; something like 11V to 18V input with tolerance for 40V spikes.

I don't know if the SIG60 chip itself has a regulator but that evaluation modem does (10V to 36V input).
