Mathjax is a cool library - http://ajaxian.com/archives/mathjax you can display latex formula webpage,
when i attended some meetings in NCERT, Math teacher who were having a good knowledge of math told me some problems
1) Kile or Latex2html generate webpage but they put image for using formula instead of MathML : So Student can work on this idea, they can add support of MathML into latex2html using mathjax library - It won't take much time to integrate
2) Geogebra animation : I have not tested but they were saying , you can export animation from Geogebra and it will be using java. Those who want to work on a project can take this idea to modify geogebra and create SVG animation , I can give help because i have already worked on SVG animations
3) HotPototos alternative ? HotPototos is a proprietary tool. you can store MCQ and generate objective exam, I do not know the alternative but if you want , I can guide for this project.
