With advanced HTML you can imagine scalable interactive SVG maps,
science texts with interactive JavaScript + <canvas> physics simulations
(like the WIMS stuff but running in the browser), biology texts with
layers that show and hide different anatomical systems... All with quiz
modules that work offline and online.  Unfortunately collaborative
editing on wiki pages and Flossmanuals doesn't support that level of
interactivity, and the people with skills to do it are rare.

Heh, http://ejohn.org/blog/processingjs/ is the Processing language
running in a <canvas>.  Works on XO, slowly.  (I hope XULRunner 1.9.1
with the Tracemonkey JIT shows up in joyrunner builds.)

There is no fragmentation, the XO ships with XULRunner.

I worked at Macromedia for 9 years, I know well of Flash's many
benefits, and many downsides for OLPC.  Rather than debate it, if
there's Flash content relevant to OLPC's mission, mention it on the
wiki.  A few days ago I added a brief mention of the SWF format to
http://wiki.laptop.org/go/Image_file_formats before I noticed someone
had already put it under "List of objectionable formats" on the talk
page; I don't care deeply either way.
