CeBIT and Powerline seem to have a thing for one another, and sure enough, this year we're seeing yet another firm storm onto the scene in an attempt to advance the flagging technology. London-based En-Twyn set up shop in Germany to showcase its En-Compass, which doesn't require any special wall cutouts and differs from most other Powerline systems by packing its electronics on the backside. In other words, you won't have any unsightly adapters protruding from the front. Beyond that, everything else works as expected -- Ethernet signals travel over your existing home wiring setup -- but unfortunately, the product is still stuck in prototype stage at the moment.
