Wow! This is great Carsten.
As you know, I have spent the past week preparing a set of lectures
for one of my courses completely in org mode using beamer. I finished
them today (100 or so slides) and the way I set it up is working quite
well for me. Mind you, you've added a few features that will
definitely come in useful and I am going to retrofit back into this
set of slides when your update is available.
I do like the whole setup you've defined but I have a couple of comments:

I've modified *my* interpretation of level 3 headings to take the text
given on this heading as the option to the columns environment so
that, for instance,
,----
| * section
| ** a slide
| *** [t]
| **** 0.4
| - one column
| **** 0.6
| - another slightly wider column
`----
will generate
...
\begin{columns}[t] % note the [t]
...
as I found this necessary sometimes. Although this looks a little
ugly, I am not sure if there is a better way of passing these types of
options to the columns environment?

You may wish to make it clear that this will be relative to \textwidth
as currently defined at that point.

This is really nice! As you know, I was using level 5 for blocks
which meant that they had to be in columns (although obviously I could
have one column of full width). This is much less clumsy than my
approach.
One last thing: would you like to mention support for \alert{} or does
this belong elsewhere?
Thanks again,
eric
