Taking off requires a upward net force. This is caused by LIFT. So, with Newton helping us out a bit here, we will prove that the plane cannot take off:
Starting out, at v=0, the plane is not moving through the air, hence the total net force is still a vector pointing DOWNWARD (this is the airplane's weight). When the airplane starts moving (by providing forward thrust) the conveyor belt reacts and does not let the plane roll forward RELATIVE TO THE AIR. Velocity relative to air is STILL zero.
Key point here: if the airplane does not move THROUGH THE AIR, the lifting force is NOT generated.
And thus the airplane does not take off.

Let's take your sea plane analogy and try to take off in a raging river. Say the river ALWAYS matches the speed of the plane, but in the opposite direction. Just like with the conveyor, that plane will never get up. Same with a ski plane if you put it on snow that is always moving at the same speed as the plane but in the opposite direction.

My .02 cents worth, we are still at the lounge.

OK I lied this is my last post.
Hoss you might want to check this out. http://www.avweb.com/news/columns/191034-1.html
I hope the link works.
I'am not even gonna say if it will fly or not. My head hurts.

OR:
The plane can take off only under these circumstances.
If the engines were routed directly infront of the leading edge of the wing thereby creating pressure difference between the top and bottom (lift) of the wing effectively making it a vertical takeoff machine

Hoss, You are a very intelligent man (should have gone to Baylor, buts that's another story 
) think this through before you type another post.
To your theory, you are correct if the wheels are driving the plane. BUT the wheels are not driving the plane. The engine is pushing on the atmosphere independant of the conveyor. The only way to cancel out the forward motion of the thrust of the plane is to tie it down or create a headwind to match the thrust, but even in the latter senerio the plane would lift off at rotation (lift off) speed and fly. (ground speed 0)
