If you plug this into your pc, it will free up hard drive admittance and the network will all speed up.. but the adaptor hasent been invented yet, guess the manufacturers have high hopes..

will the threads screw into a 1 1/2 threaded fitting?

Yes, this screws directly into a 1 1/2" pipe threading. It also comes with an adapter for a 2" pipe.

what is life span for mini vent

We just replaced two, both had replaced vents that were about 8 years old.

Are these suitable for exterior vent pipes?

My understanding is they are only for use inside. They eliminate the need to connect new fixtures to the main stack.
