Works very well actually ... my studio is about 75m away from the house 
where the main network is and I use the 200Mbps version (devolo dLAN 200 
AVeasy).  It tells me that it's running at 131 Mbps upstream and 98 Mbps 
downstream.  And that's bridging multiple mains circuits in the house, a 
75m run of 45A armoured cable, and a second trip-switch box & RCD in the 
studio.

It's much less reliable when you start running it down standard 13A 
extension leads, rather than plugging the units directly into the wall 
sockets.  I suspect this is partly due to the network running through 
little 13A fuses (maybe some audiophile grade fuses would improve things ;)
