Liminality is definitely worth watching. Aside from being the only .hack story that takes place entirely in the real world, it also provides a lot of insight into the mysteries of The World.
I thought it was alright, and it does inform you what goes on in the real world, effects, etc. But, it's not really necessary to watch (unless you're curious about what's going on IRL).
I suggest getting it if you like little goodies/extras and more info.
