Basically, whenever you remove weight from a rotating assembly, it will rev quicker since you loose some of the parasitic drag associated with heavier components... the end result is a few extra hp at the wheels, in short.
Also, I've read where so-and-so had a driveline vibration... swapped in a new aluminum shaft, and the vibe went away. Never experience this phenomenon first hand, but it sounds good.
Hopefully someone will be able to shed more light on the subject

yep that pretty much sums it up, might fix a vibration, might not, but guaranteed to lose a little weight from the driveline, which is always welcomed in performance, hinestly i wish i went with subframe connectors first, but the d/s was one of my first mods. later...
