What I said about "maybe... I goofed" was right! The 2nd documented Installation tactic for launchpadlib did succeed after Matin pointed out my mistake. Therefore, I see how Python non-Ubuntu UNIX/Linux developers have a way to integrate with LaunchPad. For the reasons stated though, I still don't know how Windows and non-Python developers could perform successful POST operations, since it seems only launchpadlib could get the realm and the consumer key to LaunchPad such that authentication would be honored.
