I think mainly what is needed is just a way to very quickly and easily get started with the library and begin using it to do something useful, even if it uses only a tiny percentage of what RDM is capable of. DMZ uses an example of a very simple auth system, as a for instance.
If RDM is able to use existing database structures with some configuration, then that's a big 'selling point' - in my pre-DMZ project I'm stuck with a hybrid system where I use DMZ for new functions and leave the original functionality in standard CI AR.
Perhaps there is some existing CI application, like perhaps one of the CMSs or auth library, or maybe just something really basic like hooking up RDM to use CI Session tables as objects and manipulate them directly via RDM. Basically show how RDM can be bolted into an existing system without requiring database restructuring (and thus program refactoring).
I think just something easy to get you in to using it for something useful is the single most important thing, as learning by clear example and then tweaking the sample is what I personally find the easiest way to learn.
The big reason most people don't use ORM is complexity and learning curve, so anything you do to drop the barrier to getting started then logically more people will get started.
