Apple Magic Touchpad

I'm more curious about a wireless bluetooth keyboard vs. typing on the screen.

Won't work.

Confirmed?

The big problem with Bluetooth is that Bluetooth isn't Bluetooth even though it's advertised as if it were. Bluetooh is a set of communication protocols (called profiles in Bluetooth speak). Any particular device generally only supports a subset:

Also, you would need to invent a mouse/trackpad cursor of some sort.

Don't see why a Bluetooth keyboard wouldn't work? Say your passenger wanted to look something up on something larger then their smart phone screen?

The car won't pair with the bluetooth keyboard. I tried with multiple keyboards w/o success.

Some people have reported having success with USB keyboards and mice, so I would think you could get a USB touchpad to work, or maybe even use a separate USB bluetooth receiver in conjunction with a bluetooth touchpad.

jerry33 is right that "bluetooth" can mean a lot of different things. However, I think the majority of the implementation is in software. At least in the case of the Model S, I would guess that's the case. The bluetooth receiver in the car is probably capable of working with a variety of peripherals, but it's up to Tesla as to whether or not they want to implement each of those device profiles (which may require extensive coding). Right now I doubt if it would pair with anything other than a phone, but we know* that even that functionality will be expanded.

*If I'm not mistaken, Tesla has promised further interactivity with phones, i.e. using the touchscreen to control music (play, pause, skip, etc.), display album art, view/send text messages, and perhaps more that I'm just not thinking of.

I took some keyboards and mice out to the car tonight. I couldn't get the Bluetooth devices to pair, but I got full functionality from a variety of other input devices, including a wireless mini-keyboard with a built-in touchpad. See this post for details (including pics/vids).
