Jörgen,

Wow, this is an exciting move in view of the plans to separate
ipython0's core from the terminal/readline. I am still learning about
pyreadline, but your description above makes me think that you, me,
and Gaël should think about using the new (refactored) pyreadline in
developing a base class for front ends that are based on a
line-oriented interface (i.e. mimicking the terminal interface).
