If you’re remodeling the beach house this year, do be sure to pick up these HDMI-to-Cat5 converters. Essentially, they allow you to keep a electronics room somewhere in the house and then connect your TV straight into the wall to get red hot HDMI hi-def content no matter where you are.
This is actually a really good idea. It lets organizations have a centralized AV office and stream content to each room as it sees fit. But you just know some rich douche will have this stuffed in his walls and never use them and ten years from now when HDMI is quaintly obsolete other rich douches will hire workers to just pull them out and plasterboard over them.
