Extending Microsoft Visual Studio LightSwitch Applications

I love the way how nuget is evolving. In particular, I'm very interested in seeing how the topic of internal nuget repositories and repository authentication goes.
Note, Microsoft Enterprise Library application blocks are now available via NuGet.
Superb content, makes me wonder just how many people know about Nuget and the potential with it. Will have to try and get more people looking at it and get an internal NuGet server up and running.
