Hi,
Two weeks ago we had TechEd Europe in Barcelona. It was an amazing event with exciting keynote, hundreds of breakout sessions and many one-on-one discussions. Though the event is over, lots of its content is available for you to watch on-line via our MSDN Channel 9 Web site. The key session on both application proxies was our "free your apps" session. You can watch it here and download its slides: http://channel9.msdn.com/Events/TechEd/Europe/2014/EM-B318
Here are few more sessions that I think would be interesting for you:
