This is great news. My media room currently has a 61" RPTV, and during renovation time a lot of speaker wire (for an 11.2 system) was done. My main A/V source is an HTPC. I thought about future upgrades to a projector, but decided against wiring 40 ft of HDMI in-wall.
I figured that by the time I was ready to buy a projector, there would be affordable alternatives to send the HD signal wirelessly to my display device. It seems the day has finally come, or will do soon. I'll wait for the technology to trickle down to lower power HTPC-oriented video cards before looking into getting one, though.
