According to this, http://www.youtube.com/watch?v=_TDlxFqZywo, it said that the Wii remotes are connected to the Wii console by Bluetooth. If this is true, maybe someone could make an application/hack for multi-purposes, such as a Bluetooth keyboard.
I think it was known the Wiimotes use Bluetooth even before they were released. Anyway, it must be hard to hack the Wii's Bluetooth receptor, since no one has ever bothered to make apps that use it :/ What this allows, though, is to connect the Wiimote to other things, like a computer, like that video showed.
