*sigh* The future is in LED's, folks... better color, no heat, very small current required, simple PSU is just fine...
Though, I am interested in seeing such a setup. I wouldn't be so worried about leaks / spillage as I would be about condensation. Leaks are easy to stop. Just apply more silicone! 😀 I suspect that a simple tank around the lamp with a submersible pump and radiator mounted on top of the thing could be a very quiet, and very nicely overkill solution. After all, what's the fun of a solution that *just* does the job? Don't you want something with more capabilities than you will ever exploit? 😀

Your design will dissipate heat from the reflector, but the heat of the reflector is irrelevant. As long as the metal on the reflector doesn't melt, you are ok.
To understand what is going on here you need to remember the law of convservation of energy. When the light energy strikes the LCD panel, a portion of the light goes through. Since energy cannot just go away, the light that is filtered by the LCD has to do something, so it turns into heat energy. Heat is being generated right at the LCD panel.
Alot of the heat comes in the infrared portion of the light spectrum, so if you have an IR filter, you should block a substantial amount of heat hitting the LCD.
I don't think heat is as big a problem as you think it is.
With a couple of beefy low noise fans, you'll be alright.
But the trick for uglyness, and light leakage, and noise is to put your projector in a separate room. This is the setup that I am working on. Im still building / designing my projector, but when Its done, I will definitely post pictures.
About the sunlight funneling thing, I've always thought about something like that.
I don't think that we know enough about light to do anything like that, and actually make it functional just yet. You would need to follow the same priciples of fiberoptics, except instead of a wire, you would have a large pipe. You would also need a huge funnel ontop of your house, with a chip in it to calculate the location of the sun based on the time of day and day of the year.
Most people watch their projectors at night time though, so I don't see how that would be useful...
It would be really high-tech to see it though
