MoonRay, one of the developers over at Joomlaspan.com has been developing a lot of useful tools for Joomla. We use his Google Translation module on the right side of our site, and it really gets a lot of heavy usage.

He uses the Simple Machines-Joomla Bridge on his site and has been kind enough to publish a tutorial, explaining how to overcome metadata problems caused by the integration. You can see the results live at Joomlaspan.
