Progress so far - I have plumbed into the Aerial circuit that my house is wired with successfully (at least for a minimal system). The first point to note is that the wall sockets with the coax connector do not connect straight through to the lead (at least mine did not). There are capacitors in series, so the first thing to do is short out the capacitors on the back of the socket. A trivial operation assuming one has a soldering iron. Having sorted that I have connected my PC to one socket with a DS18B20 in another at the opposite end of the house and it appears to work fine. I don't know the exact layout of the wiring but it must be at least 30 metres. Only a very simple network so far but a good start.
