Thank you. There is a tool for accessing Akshell: http://www.akshell.com/docs/guide/using/#tool

You can use it like this:

sudo easy_install akshell

akshell get your-app

# make changes

akshell put your-app -e "test()" # send changes and run the test() function

It can be integrated into an IDE (I use it from Emacs). But it isn't a substitution for a version control, which wouldn't be handy here because of short put cycles.
