I was thinking of more along the lines of build the needed AI system Using Rain inside of unity and then when all done and said export the needed AI files to the server to perform needed functions and such. You can DESIGN it in RAIN on the unity client side and then just export the AI files to the server for actual execution. Keep the tables/values stored in a database file of course and then just access once server starts up. AI writes would require a server restart but shrug its better then trying to design a whole new system from scratch.
