One of the best kept product secrets in the AV industry is a product from Peerless-AV — yes a mount company. It’s called HD Flow (www.hdflow.com) and it allows you to send HDMI signals (up to 1080p) wirelessly over an 802.11n network up to 40 meters. But, it doesn’t just do one-to-one HDMI; they even have a version that takes two HDMI inputs (and even one component video input) and sends them to up to three different HDTVs or HD capable displays.
