I did this about a year ago, but doesn't really extend or care about rails at all. http://obvious.retromocha.com http://obvious.retromocha.com The only "framework" part that you need outside of some reasonable OOP design principles is some amount of type checking to enforce some notion of boundaries. Ruby is super weak in this area, so I added some bits to do that. For the record, until you experience the trouble that the MVC Big Ball of Fat Models or Controllers gets you to, you probably won't have much appreciation for the service/command style or the hexagonal ports/adapters style. At least, that's been my experience with other developers.
