Create a complete WYSIWYM suite, with :
- a text document editor, based on Lyx (perhaps a fork)
- a WYSIWYM Beamer editor (see http://en.wikipedia.org/wiki/Beamer_%28LaTeX%29)
for handling presentations (Lyx does it, but not as well as it could be, and I think a separated program is needed)
- a WYSIWYM data manipulation program (instead of using WYSIWYG programs as Ooo Calc), perhaps based on R. The idea is just to handle databases, to say what are the relationships between each row/array, and to generate separately the presentation of final results (graphics, tables, charts)
All of it with a revision control system that aims to collaboration, and perhaps network abilities for simultaneous work on the same version.
