Wireless printer ports to support USB cams

What I would like to see is a mod for one of those little wireless printer port boxes, you know, the ones that you hook up to a USB printer to make it wireless... Anyway, the mod would be to allow it to take a web cam instead of a printer and turn your web cam into a wireless cam that can be placed anywhere. The mod would have to be less expensive than buying the typical wireless cam (~$150.00). Has anyone ever attempted to do this? Would someone like the challenge?? For all us financially limited folks out here, you would be praised and raised to god-like status.... =)
