Aloha Carsten,

I've had a chance to look at your first draft of beamer support.   
You've done a terrific job.  So much of the draft is right that it  
helps to focus thoughts on the parts that are candidates for  
discussion and possible change.

Along those lines, I don't think using headlines for  
\begin{columns} ... \end{columns} works very well.  I think headlines  
should be reserved for sectioning, frames, elements of frames (blocks  
and friends), and notes.  Once a headline level has been designated  
for frames (n), then headline n+1 becomes an element of the frame, and  
headline n+2 becomes notes for the frame (following Daniel Martins'  
lead).

To my mind, columns are attributes of a frame, so they might better be  
handled as a property of the frame.  Frame elements are specifically  
assigned to a column, or not, using a property.

Roughly, this would yield the following syntax, which ought to export  
fairly cleanly with the HTML and LaTeX exporters.

#+BEAMER_FRAME_LEVEL 2

* Section 1
** Frame 1
	:PROPERTIES:
	:FRAME_COLS: 2
	:END:
*** Element 1   :block:
	:PROPERTIES:
	:IN_COL: 1
	:END:
	- Item 1
	- Item 2
**** Notes about Element 1 block
	- Keyed to Item 1
	- Keyed to Item 2
*** Element 2   :block:
	:PROPERTIES:
	:IN_COL: 2
	:END:
	- Item 3
	- Item 4
*** Element 3
	This element spans two columns.  The headline doesn't appear on the  
slide.
*** Element 4  (headline doesn't appear on the slide because not a  
block or friend)
	:PROPERTIES:
	:IN_COL: 1
	:END:
	- Item 5
	- Item 6
** Frame 2
  *** Element 1
	- Item 1
	- Item 2
   **** Notes
	- Note for item 1
	- Note for item 2

Thanks again for drafting what should be a very useful addition to the  
already insanely useful org-mode.

HTH,
Tom
