I felt guilty about this at the time but forgot to mention it. It seemed like having some usable packages would be nice, but maybe it doesn't matter if we simply verify that the pieces connect together in this integration test, and catch the real use cases in lower level tests.

If we did want real packages it's a tricky one because I'm extremely against checking binaries into DVCS and an external dependency to fetch them from isn't nice either. 
Therefore if we need packages for any tests, my preference is to run "nuget pack" on some empty files called "something.dll" to test the integration of the parts
I'm ok with either having 0 packages, or having 1 or 2 dummy packages made during the test. Do you have any preference?
