You could just run the Receiver Manager software on a Windows server with an HPNA card, and then HPNA should work fine. Are you saying that Linux is a requirement for you?

I wouldn't count on the phone-line-over AC working with HPNA. I'm pretty sure you need the physical connection for HPNA to work. The AC stuff only works for low-frequency, low-bandwidth signals I'm guessing.
