Is there a limit to how long a controller cable can be before performance begins to degrade (specifically for Xbox but I suspect this applies to any)? Here's the story: My next HT is going to have my equipment rack in a separate room, and I would prefer to have my Xbox there as well. The current crop of wireless controllers don't impress me - I really prefer 1st party controllers and don't know what Microsoft has in the pipeline. Would it be possible to run extension cable to four external "ports" in the theater proper? Then I could use the standard S-Controllers, Communicator for XBL, plus other external peripherals should I add in the future (ex. wheel, Steel Battalion).
