Possible to connect to a HTPC as a bluetooth Keyboard?

I've got a Sofabaton U1, and it's doing a great job in the situation I'm using it for, but I want to plan ahead for when my harmony remote contriling my HTPC goes out. In order for it to most easily control the HTPC, I'd like to connect the Sofabaton to the computer via bluetooth and have it operate as a bluetooth keyboard. Is this possible with the U1?
