Use a shortcode to display custom meta box contents

Question

Is this possible? If so, can someone point me towards a clear tutorial? I have a column of content I want to float right of the_content, so I'd like to be able to use a shortcode to put that content in the post for a page.

I've found the following (but want to modify it for get_post_meta):

function get_custom_field_fn() {    
 global $post; 
 $custom_field_value = get_post_meta($post->ID, 'cf_name', true); 
 return $custom_field_value; 
} 

add_shortcode('cf_name', 'get_custom_field_fn');

I'm guessing that I need to change a few things but not sure which things to change. My custom meta boxes will have 8 fields. I'm also guessing that my shortcode will need to allow for the post/page ID and I also need to interject some HTML in the function.

yeah, the question is a bit unclear. but i think you need shortcode attributes

function get_custom_field_fn( $atts) {    
global $post; 

 extract( shortcode_atts( array(
        'meta' => ''
    ), $atts ) );


 $custom_field_value = get_post_meta($post->ID, $meta, true); 
 return $custom_field_value; 
} 

add_shortcode('cf_name', 'get_custom_field_fn');
