Working on a multiplayer turn-based RPG and I'd like to have the option for host migration so the game doesn't stop if the host is somehow disconnected. I am obviously using a client/server model so I'm thinking about just sending out a server state packet every second or so that just sums up the entire game state as the server currently sees it. If the server stops sending packets then a client is choosen to become the host and it just uses the last server state packet it recieved. Are there articles I can read that discuss this topic, or can anyone offer up some helpful advice to avoid some of the more common pitfalls? Thanks.

This would imply that the clients know everything. I thought about this, but in the end it is very dangerous... Hackers can cheat extremely easily.
