Hi Taylor, I think it's almost impossible to determine the originated IP, because every time Google uses a different server to request, and in theory only the requested ends (Twitter) can see the originated IPs.
My app is http://v2ex.appspot.com/ , now is still experiencing the problem from time to time. I guess the problematic requests are made via basic auth, or you can easily deactivate its consumer key, right? Now I'm long for August 16.
