A point of clarification. The Notebook and Cell objects would not be
for the execution of python code. The execution logic would simply
out of the Notebook, extract the python code (as a str) and return the
[Thinking out loud about what this might look like in a web
browser....more thought needed]
The Python Notebook and Cell objects would not be pyjamas entities - that
Notebook and Cell
objects would live in the web server and be capable of rendering
themselves as json
The pyjamas classes would contain the logic for the user interface,
and calling out to the
Notebook/Cell web service and pass XML/json back and forth....

Yes, that might work. I have been thinking about the Cell objects as having
all the logic needed to render itself in various formats. But maybe a
itself could be lighter weight - the rendering logic could be a separate class.
Then the Cell objects could be compiled to JS using pyjamas. But I am
with how pyjamas works enough to see if this would work.

Definitely don't wait for me to implement my idea...I do agree with
your statement about
the ease of parsing XML though.
