On the config options side can I recommend a decent Dependency Injection framework will make your life a lot easier, as you can have everything configured at startup without having lots of 'if's in the code checking the flag state. Combined with good abstraction this can make the whole thing much easier to manage and the whole config for a given client can be checked in one place.
