Going hand-in-hand with his do-it-yourself in-wall touchscreen, Mavromatic shows us a neat little wireless access point by On-Q that integrates a Motorola WAP into a convenient in-wall installation. For roughly $400, (or your least favorite appendage) you get a custom booster antenna and a device that looks like just another smoke detector. You'll still need to run a CAT5 cable to the device, so this might be more ideal for a house under construction. Check Mavromatic for ordering details, if you're interested.
