Override database config for WordPress multisite in WordPress

Just came up with a solution to this issue posted here https://stackoverflow.com/questions/12958123/override-wp-siteurl-and-wp-home-for-wordpress-multisite/

Basically you dot copy the wp_site and wp_blogs tables to your development installs when pulling in a production database, and have pre-configured them locally for your development URLs. You then leverage a network-wide plugin to set the WP_SITEURL and WP_HOME values based on configuration in wp-config.php.

Will likely turn this into a plugin once I have time to test it further.

Hope that helps!
