Sample Theme Options page for Multisite – what to consider

I could take advantage of get_template_part( $slug, $name ) and use it like:

get_template_part( 'theme-options', get_current_blog_id() );

Say we are on blog_id 5, if theme-options-5.php exists it will be loaded. If not theme-options.php will be loaded as a fallback. Please note that get_template_part is using require.
