I’m using add_meta_box() but want to include TinyMCE editor *and* Media Uploads for each box

I’m using a very lightweight plugin called WPAlchemy that lets me rapidly create meta-boxes for posts and pages. I’ve ben able to convert <textarea>‘s into rich, TinyMCE’s editors just fine. The problem is, I’d like to include the Media Upload buttons for those metaboxes / editors.

I’ve been able to add the buttons above each TinyMCE editor but when I click “Insert into Post” it isn’t (has no idea) which <textarea> to insert the requested picture/media. For reference, I’m adding the following line above my <textarea>:

<div id="media-buttons" class="hide-if-no-js"><?php do_action( 'media_buttons' ); ?></div>

I’m aware this isn’t valid since I’m using the same id, (#media-buttons) as what the default content editor uses at the top.

Someone suggested the following JS code to kinda hook and grab the src but I can’t get this working for my scenario. (Suggestions came from here http:(slash)(slash)farinspace.com/multiple-wordpress-wysiwyg-visual-editors/comment-page-1/#comment-3552)

Finally, I’m attaching an image of what it currently looks like, but it just doesn’t link the “Insert Into Post” button with the currently focused metabox. Image: http:(slash)(slash)cl.ly/4BMf

Any help, please?
