Wow! Really interesting post. I've always wanted to set up a mesh network, just for the learning experience. Just one question I've been wondering: How much do you think the whole setup would've cost if you did it yourself? I ask because I've always thought that the cost of the special hardware for a mesh network was the major limiting factor.
