Jim, any of the 5ghz hardware supported by firmware images will work. Problem is that manufacture's inventories are running out of the "XM" hardware that the available firmware supports. Chances are that most hardware you purchase will be the new "XW" hardware. Buying used 5ghz on ebay would increase the chance of firmware compatibility.
The NanoStation M5 XW has availability with beta images available over at www.aredn.org and would easily work for your needs--weighing in that beta images introduce some risk. (There's also ch -2 on 2.4ghz beta.)
The rest of the 5Ghz XW hardware will still take time to have firmware images available. The root cause is a hardware chip issue. The fix-workaround is in the linux kernel at the driver level to magically reset the the physical port (which locks up in hours).
Take a look in the "RACES/MOU News from around the county" section of this newsletter. We've been doing similar with video streams here in Orange County. We had 6 video streams feeding into the Orange County sheriff's mobile command center (think semi-tractor trailer with huge slide outs and a dozen HD screens). we had multiple video streams over both 5ghz and 2.4ghz links in a congested down town area--it works.
