Well, if the router "repeats", it would have to do so on a different channel, 
or else you'd get interference...

Even analog ham-radio repeaters do this: they repeat between to different 
frequencies, or else they'd jam their own input...

   It might even
be feasible to setup Wifi access points on the poles,
 rather than inside the gondolas (which would remove the problems of
 access points moving around: in that case, only the receivers move, but
 not the APs). Potential problem: will they withstand the cold?

 That was my other idea.  Now that I am becoming more aware about the
 hopping issues, it might be the best way to go.  It does provide several
 advantages, such as a non-battery source of power, and reduces the
 overall cost of the system.  Weatherproofing them is tedious but should
 be doable. Operating temperature on the routers is unfortunately 32F (0 
 C), which is nowhere close to what I need. 
Indeed... And you would also need to protect against humidity (really 
waterproof boxes... and then you'd still need to worry about condensation)

  I suppose i could put a 
 heater inside of the little "box" or whatever. 
That would be an idea.

  Also, did anyone on the list have any interest in my
request for a bid
 or estimate for the update program?

Which request do you mean?
