Combine honey, cream, and vanilla seeds and pod in a medium saucepan over medium heat. Bring to a simmer, and cook, stirring until honey dissolves. Remove from heat, cover, and let stand for 20 minutes.
Place chocolate in a food processor. Return cream mixture to a simmer, then strain through a fine sieve. Discard solids. Pour cream mixture over chocolate, and let stand for 1 minute. Process until smooth. Add butter, and continue to process, scraping down sides occasionally, until butter is incorporated. Let cool slightly, and then use immediately.
