Does the hidden node problem handle this?

I haven't read about this since the very early days of wifi.

Three nodes in a line, with the middle one on a hill and can see the other two. 
The two end nodes can't hear each other. The middle node figures out that it's 
the relay between the two end nodes and sends packets out all antennas.

At least that's what I remember.

It is worth buying a piece of Al foil backed insulation and cutting a slot, big 
enough to push your wap into, with one antenna on the inside and one on the 
outside, and putting the whole thing in the door of your faraday cage?

Alternately, can you put a 6" square skylight window in your door?
