Overall this looks good to me so far.

It should be possible add unit tests, at least for the upload error reporting.

@stevensJourney, I've added 2 simple sync status tests which are just a minor extensions of the existing stream tests we have. They are under web for the moment, but I think we can do some work/mocking in the future to be able to move these kinds of tests to common.
