Display Page Tabs as a Menu Block

I would like to be able to display tabs/context links from user/* in a menu block.

Does anyone knwo if there is a module that would do this, or if not how I might add this into a custom block.

In my theme I tried adding <?php print render($tabs); ?> to region.tpl.php and adding in some of the html that would wrap it as a block, hwoever when using that in the region.tpl.php file, it doesn't render out any of the tabs.

Any suggestions?
Thanks
