Oh no you did-enn!
I noticed you posted this earlier, then wussed out and now I see you've decided to risk it.
Anyway, no. It's not possible. Even if I were inclined to make it possible (which I am not), I don't know if it is even possible to make something that is at its core, a UI driven entity, into a service.
At least now if anyone else dares to ask this, I have a link I can post...
