I'd start looking at companies that offer BPL (broadband over power lines)...with the ability to offer power, data, voice over one line that'll eliminate the need for dsl, cable, telephone lines, etc. Each outlet is a recepticle (uses the same lines) for everything so no need to rewire and no need to run wiring to dedicated rooms.
Also nanotech companies have fallen by the wayside as for years analysts have been trumpting their cause and people stopped listening...there's a lot of upside but too much hype too early.
