It appears all that I really need is an option added to keyclone that makes it _not_ modify the resolution entry in config.wtf. I've manually gotten around this by locking down the file at the OS level and setting all clients @ 1920x1200 (but I have to put in my login name per client). Switching secondary regions with the primary region now happen instantly because the client doesn't have to mess with trying to resize it to my primary screen resolution.
