Mmmm, I can understand your interest in such a system, but I strongly doubt it will ever happen. Why is that? Because "Sons of Cimmeria" was implemented in response to the high level (a flood really) of criticism Mongoose received concerning editing mistakes on the Conan core book.
Now, I'm still waiting for my copy, but from what I hear, the editing is almost perfect on this one. So - and I'm sorry to burst any bubble here - I doubt we'll see a "Sons of Magnamund" program. Don't forget that Mongoose is still a relatively small company (growing, yes), so they hardly have the ressources to build such a program for all their lines.
