I am going to cross post this in the DIY forum, for obvious reasons. The final cost was slightly over $500, which is not bad considering the cheapest I could find it premade by someone else was $3200! So here we go, pics of the final results, followed by what I did to get there.
Flush against the wall
Side view against the wall
45 degree angle near the wall - perfect for playing the Wii or anything which requires a LOT of room
In the center of the room - it is at a 90 degree angle compared to when it is against the wall, EDIT: WOW! Due to being so much closer, it almost looks at big as the screen - it definately is not.
Rear view of the mount. It is a Sanus LC1A Ceiling Mount $130
Here you can see the Cable Carrier Chain by IGUS - what I call the tank tread part IGU-E08-10-028-0 $100
Johnson Hardware 200SD Commercial Grade Sliding Bypass Door hardware. Two 6 foot rails, four rollers, two rail mounted door stops, wrench $200
Here you can see two pics of it all mounted. I used 3/4 inch one hole strap to hold it to the ceiling, I used electrical tape on every other or every third knuckle to help ensure the wires stay inside the chain. Home Depot in the electrical parts $2
The cover was fabricated by a local metal fabrication shop. It is aluminum and has piano hinges on it so I can open them to get inside. $70
The door rollers were mounted onto the ceiling plate of the Sanus mount, the extra bolt length sticking through the mount was cut off flush. The two door rails were mounted onto the ceiling. This was easy for me as I have a double layer ceiling - the first layer is 1/2 inch OSB and the second is 1/2 inch drywall (with Gree Glue between them). This meant I did not have to try to find studs to mount the rails. MOUNTING TO STUDS IS VITAL!!! There will be a lot of weight on these rails. The rails can each hold a 400 pound door, so the rails and rollers will not even break a sweat. Two rails are used to ensure there is no side to side wobble when the TV is moved, not for the weight.
After the tracks were on the ceiling, the ceiling plate/roller combo was slid onto the tracks and rolled back and forth to check for binding - adjust as needed. There are 14 holes on each 6 foot track, and I used 14 x 1 3/4 wood screws to attack it to the ceiling.
The wiring was run through the ceiling, between the two rails. Both the electrical and the HDMI cables were run through the carrier chain, which was affixed to the ceiling from the entrance point to the center point by the one hole straps (4 of them). This provided strength and stability to the chain. MAKE SURE THE CHAIN IS LYING SIDEWAYS, WITH THE OPENING PARALLEL TO THE CEILING! If you have the opening facing the ceiling, the chain will dropp and hang very low, causing binding and ugliness...as well as gnashing of teeth and much lamentation! I used tie wraps to ensure the cables could not come out in the part affixed to the ceiling. Tie wraps caught the rollers on the other parts, so I used electrical tape on every other knuckle to do the same thing.
I had to tie wrap a wood shim on the inside of the rollers to prevent the chain from between the roller and the mount and binding. I had a lot of wood shims left over from installing a door. Basic parts list:

Some minor touch up still needs to be done, and the end cap needs to be painted and installed, but everything works as I wanted it to. I kept the entire thing a secret from the wife who LOVES it. Edited by cybrsage - 6/11/12 at 6:33pm
