It annoyed me that all the minor nations basically had to research and manufacture everything themselves. I would opt for the ability to PURCHASE arms and equipment from other nations. Of course, the system would require some sort of limitations so that exploitation would be harder to do.
I suggest a limitation based on countrysize and manpower, and probably tied to amounts of free resources as well. A formula could calculate an upper limit to the amount of each unit possible to purchase, so that Cuba doesn't end up with an armada rivaling the Royal Navy.
Exchange of technology between allies should also be a lot more automatic, and not tied to random diplomtic options.
