I will do reST import/export, but having it the default format, that I
think sucks. With xml, anyone can easily write a parsers for it in any
Besides, I need to push the worksheet to the browser. In my case, I
use pyjamas, so it's pure Python, however, exec/eval are not evailable
there (as far as I know), but I am sure xml would work, here is some
code to handle xml in pyjamas:
I think, that it might work to push the whole Python objects somehow
(that's the nice thing about pyjamas, that since you have python on
both sides, you can do lots of cool stuff), but maybe not.
I like Brian's idea to be able to just import it in Python. But I
think I'll just stick to xml for the first iteration of my notebook,
to get the job done.
