Beamer 2-up with projected frame above and notes below

Question

How can I create a printout of my beamer slides 2-up, with the displayed frame on the top half, and the following \note{} frame on the bottom half of the page? If there is no \note{} page, the bottom half should be blank. If I do \pgfpagesuselayout{2 on 1}, pages without notes remove the alignment on a single page between a frame and the corresponding note. This is exactly what I want, except I'm not handwriting my notes on lines, I'm using \notes. Judging by the comments on that blog, I'm not the only one who'd like this feature.

Answer 1

This should work, without using the other .sty file. It's arguably an abuse of how you'd keep a second screen of notes while you were giving your presentation, but it works and is very simple.

\documentclass[handout]{beamer}
\title{The Title}
\author{The Author}
\usetheme{Copenhagen}
\usepackage{pgfpages}
\pgfpagesuselayout{2 on 1}[a4paper,border shrink=5mm] % could also use letterpaper
\setbeamertemplate{note page}[plain] % Beamer manual, section 19.1
\setbeameroption{show notes on second screen=bottom} % Beamer manual, section 19.3

\begin{document}
\begin{frame}
Here's some content, with no notes added.
\end{frame}
\begin{frame}
Here's some content, with notes added.
\end{frame}
\note{
Here are things to remember:
\begin{enumerate}
\item Stress this first.
\item Then this.
\end{enumerate}
}
\end{document}
