SDL Tridion 2013 XP Integrations with third-party TMS


I have been searching for Tridion connectors that can integrate with third-party TMS, but have failed to find any promising solutions until now.

Does anyone know of any SDL products that can connect with Tridion and be able to import content for translations? Since Trados is an offline tool, I doubt it would have any such capabilities. 

Many thanks
