Can I emulate a Bluetooth keyboard with my Android device? I'd like to use an Android phone for controlling presentations. I know there's some wifi approaches, but often times the computer running the slideshow isn't owned by me and is not comfortable installing and running other software, especially stuff designed for remote control.

So I'm specifically looking for some way to do this using the Bluetooth HID profile, as it requires very little set-up on the PC side. Basically, I'm looking for the Android equivalent to BlueMaemo. Is there a way to do this?
Just saw this today...
AndroidSpin: Turn your Android Into a Keyboard and Mouse for Your Playstation 3 or PC


  Another reason we all love technology,
  thanks to some clever development by
  XDA member berserker_devel, you can
  now use your rooted Android device as
  a keyboard or mouse on your
  Playstation 3. The app, BlueputDroid,
  has been released in beta form and
  allows your phone’s screen to be used
  as a cursor and virtual or physical
  keyboard to input text. This app could
  also be used for your PC, for those
  that really want the most from there
  device(s). Either way it could save
  you quite a bit of money on buying
  wireless input devices for your toys
  (provided they have bluetooth and are
  supported).


A limited number of devices supported at present but it's being actively developed so something to keep an eye on even if it doesn't cover your device right now.
