Yes, excellent indeed.  

An aside: *Carsten,* I have been off ill (eye operation at start of
December) so only today have I managed to come back to play with
org-mode's beamer support.  Everything so far is working as expected,
i.e. very well indeed.

I think you need to add it explicitly with \tableofcontents?  In beamer, I 
simply typically have

--8<---------------cut here---------------start------------->8---
  \frametitle{Table of contents}
--8<---------------cut here---------------end--------------->8---

I think the decision was to allow users to customise this themselves
(as indicated in your subsequent followup with a link to one of our
previous messages on this topic).

Again, beamer supports this easily so I would suggest simply adding
some direct latex code at the start of your org file.  The latex code
I use is:

--8<---------------cut here---------------start------------->8---
--8<---------------cut here---------------end--------------->8---

You could simply put this in one line with #+latex_header: as in (untested):

--8<---------------cut here---------------start------------->8---
#+latex_header: \AtBeginSection[]{  \begin{frame}    \frametitle{Topic}    
\tableofcontents[currentsection]  \end{frame}}
--8<---------------cut here---------------end--------------->8---
