Duplicate settings of master blog to slave blogs in WP multi-site installation

Is there any smart way to set a site (blog) as a master, which settings are replicated to the rest of the sites in the network?

There are plugins like this one: YD Network-wide WPML that attempt to accomplish this, but they don’t support all settings.

There are two options I’m aware of, and neither are free:

http://wpebooks.com/replicator/

I haven’t actually tried either of them yet, so can’t recommend one over the other.
