Oh, I hope you're right. It's not impossible that the old (and new!) Ron Paul faction in the LP will be enough to swing their Convention into offering Ron Paul the LP nomination, even though he's not actively seeking it! I have similar hopes for the Constitution Party.
But, if Rudy Giuliani wins the GOP nomination, and Ron Paul does not pursue an independent/Third Party campaign, I am not aware of a Pro-Life Libertarian candidate waiting in the wings. And as I will never vote for a Pro-Abortion candidate in the General, that will leave one Party I can count on: Constitution.
However, that's getting ahead of myself. My hope is to see a combined Republican-Constitution-Libertarian Nomination for Ron Paul.
Neither am I, but this is a different case for the Constitution Party.
