Eric listed all (or almost all) "requirements" for exporting Beamer.

Some of the mI encountered a few days ago. I decided to export the
lists into latex and then converting by hand  the rest of the

I am also very happy that "Beamer" is becoming an official directive
of org-mode.
Carsten converted us to org-mode and we converted him to Beamer!
