Powerline networking

I confess that I sort of forgot about the whole 'network over power 
cables' thing until I needed network access in series of buildings with 
metre thick granite walls. And concrete ceilings.

Does anyone know if powerline adaptors (things that turn your socket ring 
into something like a LAN) "just work" or require multiple faffing 
sessions? The actual requirement is to network the various converted 
outbuildings of an old farm. My guess is that these things turn the copper 
cables into a kind of giant unswitched 10-base-2 type network. My hunch is 
that the network is shared across every building on the same loop from the 
nearest transformer - I don't see how the signal would get through a 
transformer, and I don't see why anything else would stop it. This is 
fine, as the devices appear to have some kind of security layer that 
prevents neighbours reading your network traffic.

Has anyone used this stuff?
