A bit late, I know, but here's the material and links from the Session Florian Loretan and I did in Drupalcon London 2011 last month.
The video and the slides from the session: Multilingual Drupal Solutions - Use Cases and Modules - Slides

See you next at Drupalcamp Spain in Seville, October 1st, where I will be presenting a similar session, this time in Spanish: Drupalcamp Spain 2011: Sitios web multilingües con Drupal 7.
