How do I debug remote python/twisted code from within Emacs?
The closest I got with an internet search was Geben, if I understand correctly, but it has not been maintained for a few years now.
You can try qdb
https://github.com/quantopian/qdb
An emacs interface (qbd.el) is included: https://github.com/quantopian/qdb/tree/master/client/emacs
I do not write python code in Emacs, but I would try pdb
(Emacs built-in python debugger) on a remote python file.
