Powerline box. After all, it features a four-port adapter that easily manages game consoles, Blu-ray players, AV receivers, etc., and passes those signals along your home network via power wiring. The rub? It's based on the older 85Mbps standard and not the fresher, speedier 200Mbps protocol. In other words, you may see dropped frames and the like if trying to push too much HD through here at once. Ah well, at least that news makes the Asia-only availability that much easier to live with.
Update: So, these seem to be shipping now in the US. Huzzah! [Thanks, Dave!]
