Inulin: fiber and sweetener?

I was reading an article on how restaurants are providing more low carb meals to dieters. One of the chefs said he used inulin, a fiber extracted from chicory root, to sweeten desserts.

A sweet fiber source sounds interesting for low carbers. A search on Google brought up some technical info on inulin, but no practical info. Anyone use this stuff?

One polite bump, then I’ll drop it.
