I thought I'd done my research when I built a dedicated movie theater in my basement, around 2004 or 2005. I hung a decent projector from the ceiling and wired DVI through the walls and ceiling. What I should have done was put an accessible conduit so it was replaceable. because.. only a few years later the projector was destroyed in a lightning storm, which also took out a fridge, toaster, a bunch of GFI outlets, router, etc.; and by that time, decent 1080p projectors were affordable ... and were all HDMI. so - conduit for those cool hidden in-wall wires like HDMI for your wall-mounted TV, etc. - whole house surge protector Your PoE idea is pretty good, ethernet has been around and will be for a while, and wireless will never really cut it all the time.
