Automated placement of text and graphics within presentations

The beamer package creates very professional presentations. Are there any additional packages which can be used with beamer which allows users to focus on content, while leaving TeX to decide where to place everything? E.g.:

• Users make a list, TeX displays attempts two-column mode if there are many short items.
• Users type an outline and specify a prefered density per page for the information, TeX decides when to add page breaks.
• Users link graphics to items in the outline, TeX decides where to position the graphics.

Are these features within the capabilities of beamer?

I don't think that anyone already coded something complicated like this yet. Analyzing content is not trivial and not always fully correct. It is usually simpler to decide the layout themselves and add the required code. However, I could imagine more code templates for standard frame layouts to be very useful. – Martin Scharrer Dec 14 '11 at 13:33
And I would imagine the situation is the same across all document classes. There are some options to \penalty for line and page breaks and H option to graphics but that's about it on a global level. About how ragged or sloppiness you'd LateX take care of things. – Sivaram Dec 15 '11 at 9:00
