I had the same problem. My offices are in a historical district so it's a big no no for any kind of change. Heck it takes 6 months if we want to change the colors of a wall. Fortunetly, we have friendly neigbors that allowed us to place a couple wirelsss hubs in their offices so basically I have 3 hubs and a router. This cost us about $1000.00 bucks two years ago. It might be worth while to pick up 3 or 4 of these new airport express and secretly plug them into the closets of neighboring buildings creating a secrte network to your building. Heck 100 yards aint to far. I can easily get 100 yards from my wireless hub. It's a linksys with an external ant.
