Re: Bathroom Vent - Is A Motorized Fan Needed?
I believe that those are called inline fans. I've never seen one myself, though they've been discussed a few times around here as a means to assist venting with long runs.

Above will be easiest and cleanest, below will require a small amount of wall repair when you're done. If you find fire blocking and want to get below it, I'll continue a discussion on how you go about that.
When you install your ducting, you want to make sure you slant it away from the fan so that any moisture condensation will drain away from the fan. If you're going vertical, then you need to make sure that your roof penetration remains clear if you're in a snow zone. If you vent through the soffit, then make sure you're not too close to a soffit vent or the warm moist air will just get drawn back into the attic. Lastly, you want to make sure you vent the bathroom to the exterior so that you don't have moisture problems in the attic or other areas of the house.
