You have posed an excellent academic question which may best be inexpensively avoided as you have suggested in the dslreports thread. In similar scenarios I have seen engineers put together some "bank shot" solutions to bridge networks, like when they put a wireless backbone down the staircase at the Roosevelt Hotel at HOPE 5... http://www.the-fifth-hope.org/5hwiki/WiFi . There are certainly (expensive) dual-radio combos that are of a sufficiently low enough frequency that the occasional brick wall should prove to be less of a problem either figuratively or literally. http://www.ubnt.com/ makes incredibly powerful radios... 900 Mhz at 1W can overcome some difficult masonry issues... are you using bridge-utils or is there a more recent package for wireless bridging?
