Regarding syntax highlighting, I just found a list on wikipedia of editors we can use:
http://en.wikipedia.org/wiki/Comparison_of_Javascript-based_source_code_editors CodeMirror (http://marijn.haverbeke.nl/codemirror/) seems to be the most promising. Here's the demo: http://marijn.haverbeke.nl/codemirror/contrib/python/index.html. EditArea is also good, and comes with i18n: http://www.cdolivet.com/index.php?page=editArea&sess=6ef80ec2026659ce741a8ec0f9b36605. Demo: http://www.cdolivet.com/editarea/editarea/exemples/exemple_full.html. What do you guys think?
