(note that my response has probably been superseded by Carsten's
recent message regarding beamer support in org mode but this still
might be of some interest)


I am not sure what to say!  IMO, it's not simpler although I guess it
could be more flexible.  However, you say it doesn't work?

One alternative based on your approach is to define begin and end
commands for the columns environment that avoid using "\begin" and
"\end" which org interprets.  Maybe something like this:

--8<---------------cut here---------------start------------->8---
#+LaTeX_CLASS: beamer=20

#+latex: \newcommand{\BC}{\begin{columns}[t]}
#+latex: \newcommand{\EC}{\end{columns}}

* The main section
*** An interesting slide
    \BC
    #+latex: \column{0.4\textwidth}
    - an item with enough text to show the width of the column
    - another item
    #+latex: \column{0.6\textwidth}
    - an item with enough text to show the width of the column
    - and yet another
    \EC
--8<---------------cut here---------------end--------------->8---

which appears to work just fine.  Whether it's simpler or not depends
on what you want.  I like using org headlines to be able to hide
individual columns and to be able to move them around easily.
