Silveras,
This is really great work. Even your "rough outline" for trade is realy impressive. You really grabbed the essence of the domain system. As a quick aside, what are your opinions on taking Birthright domain rules (your own or the 3rd edition effort) and dropping all references to bloodlines completely? I believe I may have mentioned before, my interest in Birthright is apllying it to the murky politics of Sembia in the Forgotten Realms. As such, have folks with divine blood at all levels of government kinda doesn't fit, and I'd like to drop that all out of the equation.
Thanks for sharing this with us!
