Hi  Cédric,

If I understand it correctly, you want to include a graphical representation of 
you headlines into you beamer file, created via tikz/pgf.
That sounds quite similar to what I'm doing at the moment, only I create gantt 
charts instead of mind maps.
As far as I can tell, the best possibility to do that inside of emacs, is to 
use custom dynamic blocks. 
Simply create your own org-dblock-write:... function that parses the file and 
creates the tikz output you want.
You can have a look at org-dblock-write:clocktable and 
org-dblock-write:columnview for inspiration.
I think using org-element-parse-buffer and org-element-map should get you what 
you need.

You can also have a look at my gantt chart creation here:
(One el file and one org file for testing)
You can probably ignore most of the file, as you don't need the complex time 
calculations I do.
Keep in mind that this is wip and I'm not an experienced elisp / org person, so 
if anyone has better suggestions, listen to them.

I will be without internet from later today until the middle of next week, so 
if you have any questions I will not be responding until then.
