Help on work Conf room / projectors

We are building a new conference rooms at work and my boss's want me to use the skills I learned (here) in my home theater for this room.


The idea is to have 2 projectors in this room since the front wall is only 9 foot tall yet its 60 feet long. Plan is to use 2 Optima HD65’s going to about a 96” diagonal screen. I need to use splitters to be able to project the same image on both.


I need a way to split hdmi / VGA / S-video / composite up in a drop ceiling (up in the ceiling)


I do this at home between my LCD and projector (produces images on both that the same time) using a Monoprice unit but this is the type of unit that sits on my rack.


I need something that can go up into a drop ceiling that will do hdmi and these analog sources (or several units).


The next problem is that the cable runs are a bit over 50 foot say the analog units might need to be repeaters. Like at home, I use a 50' hdmi cable and it works perfectly. But adding the splitter in the ceiling will allow me to run a 35' foot cable to the splitter and then maybe 15' cables to the projectors (same for all inputs). Of course trying a VGA connecton at 50' is a bad idea.


We will have a new Onkyo 606 to help with the AV along with being able to jsut directly connect a device (like cable TV or laptop) strait to the cables if we need to.


Any ideas?
