Custom fields: Best practice for list of links

[Title de-capped. Please do not shout at us]

I am a heavy user of custom fields. I am also familiar with add_meta_box technique and many plugin sollutions (such as Custom field template, Flutter, …).

Quite often, I run into a problem with lists of links appended to post such as this:

<!--POST-->
<?php the_content(); ?>
<ul>
<?php $links = get_post_meta($post->ID,'links', false); ?>
<?php foreach ($links as $link) { ?>
<li><a href="<?php echo $link_adress; ?>"><?php echo $link_text ?></a></li>
<?php } ?>
</ul>

What I need: simple UI that:

1. enables user to create a link as a custom field with “two values” (link adress AND link text). From user experience point of view, WP wysiwyg add-link feature acts great in tis manner.
2. is repetitive – maybe “create new box” ajax button would be the way?
3. would be callable as easy as custom fields

I believe I am not the only one with such issue, however I wasn’t able to find any sollution even after pretty intensive googling.

Any suggestions would be higly appreciated. Thank you!
