General Information: I am installing a projector in my church's multipurpose room gym/sanctuary for slideshows (powerpoint, easy-worship) and dvd playback from a computer with XGA (1024x768) resolution. I have a 180" screen 65' from where the projector will be mounted in the rear wall. I am interested in Hitachi's CP-X608 because it meets my output requirements and has a lens that will work for my application. The Problem: Due to the facilities multipurpose nature all equipment must be set up and torn down every service. That is why wireless would be nice. However, so far in my research it appears wireless is only fast enough for VGA (640x480). I can hardwire the building if I have to but it will be a run of at least 200'. The Question: Is wireless b/g fast enough or is there some other wireless protocol that would work? If I have to hardwire the building I want to allow the option to upgrade hardware without re-running cables. Will Ethernet be fast enough for HD or should I stick to DVI or HDMI with some sort of amplification hardware due to the long run? Or, is there another solution that I'm overlooking? Thank you in advance for any help you can offer.
