What you want to do is possible.
Buffalo has the best technology as far as I know, which will allow you to
bridge multiple devices.
Depending on how many floors you have have, you can bridge (using WDS) six
devices coming off of one(i.e, if you have four floors, you can bridge three
devices off the main router going up and then to go across the floor, you
can bridge up to 5 devices off of each bridge).
You can use a laptop running windows xp to perform a simplistic site survey
and where the signal drop, add a repeater/bridge to boost it.
