I aggree with David that having the ConTeXt presentation feature
without needed javascript would realy be great.

Pdf is a standard, but not javascript.
It's realy nice to come to a seminar only with a pdf file without 
worrying about which pdf reader tool exists on the host computer.

- Even with acroread 6.02 on osx there is some problem with some button
   (I don't remember which problem, but I just remember it's not 
reliable);
- Also Preview, the fastest pdf reader on osx (provide by Apple, then
   the it is standard pdf reader on osx) don't support javascript;
- linux doesn't have pdf+javascript reader.

So I think that ConTeXt should provide a mean (option in textexec)
to make pdf-only version of presentation.

Finaly there could be three output levels for pdf presentation :

1 - presentation step using javascript (with allow blinking, merging,
     zooming or other nice flashing features ;-)

2 - presentation step without javascript (one pdf page by step)
     => Good format for presentation by foreign pdf reader

3 - pdf file one pdf page for each final step by page
     => Good format for printing 2up or 4up slides
     This third output would also allow to print a "slide + comment"
     version of the presentation for the speacker.

The option of texexec could be something like
	--pdfonly
instead of --pdf, or simply
	--use-javascript=false
