Thanks Aaron, I will try something along these lines. This avoids the
latency concerns mentioned by Nuria, and it is very flexible - we'll see
how painful it is to aggregate the data on the backend.
(will need to be stored in a cookie and reset at loads of step 1)
We don't even need this part since UploadWizard is a single-page
application with no page load between the steps, so we can just store the
token in memory.
I don't want to log userids unless we really need them, so I'll just go
with initial timestamp + random number. I don't think connecting separate
upload attempts by the same user is particularly useful at this point.
