Ok, that makes perfect sense for building a network the way you are, but if the project were limited to that sort of hardware you will have a huge decrease in users experimenting with it. users need all three client capabilities (2.4GHz, 5GHz and ethernet), so sticking with a relatively cheap device that will do this will keep things relavent to many more people. If this can be done on equipment that they can find in local stores, as opposed to having to special order it, that's another big boost. for now I've dropped their equipment off of my vendor list, the only dual-band equipment I see from them is in the $250 range David Lang
