We did the same for 1, we have a service that picks up messages from a queue and drops 95% of them. In Python, at least, it was really really ugly. We had the alternative of using refinery, since we're on honeycomb, but didn't want to get stuck with something that only works with one vendor. I don't understand 2, though, that should be easy? You have access to the span and you can set its status code to 0. With the Python SDK that was trivial for us to do. The one thing I really hate about the Python SDK is that there's no simple way to say "attach this attribute to the top level span in this app". That way, when you get the user id further down in your app, you can just annotate the top level span with it. Thankfully, honeycomb has any, any2, root, parent (that allows you to filter on any span in the trace, or on the root or parent) but that's slow and again, vendor specific.
