Quite frankly, neither of these products is going to get much traction in the home networking market - especially at $130 per adapter - but that's not really where Corinex is aiming. The company sees the main market for these products as the same one it is currently serving with its first-generation CableLAN and Powerline products - primarily hotel / motel and apartment buildings.
Those applications have environments that desire broadband Internet access and require it to be distributed via existing wiring, but are perfectly happy to handle it centrally. This means that in-building coax won't have cable modem signals on it and DSL will also be kept off phone wires. And since installation is done by contractors, any required filtering can be added while they are on site. The other thing this market has is the tolerance for higher cost, since installation expenses can be recouped through increased rents and / or separate fees.
In spite of these negatives, Corinex' AV line still has the highest speeds of any wired "alternative" networking technology that I've seen to date. But until CopperGate makes the underlying technology robust enough to handle what might be encountered in typical home phone wiring, Corinex is playing it smart by focusing their AV Phoneline on applications where it can play to its strengths.
