I've had a chance to look at this gem. Its documentation is pretty extensive which is always nice to see. I'll consider covering this gem in the future. One thing that I highly dislike about this gem is that it seems a lot more invasive in the models. It also has a lot of added complexity based on the documentation and I'm not convinced that it's necessary to accomplish what they're doing. Overall the gem does look pretty cool and for a large complex app, this may be a good fit.
