Hello,

One easy way would be to use a RPC system. Pyro implements one of them.
See http://packages.python.org/Pyro4/tutorials.html

This could be achieved in very few lines.

Your script create a thread in which it serves the remote requests.

xmlrpclib is another popular RPC package.

Another solution is to use a web server (sounds overkill but it isn't).

A lot of python web frameworks allow you to create such server in very few lines. look at http://www.cherrypy.org/ for instance, use their 'hello word' example and replace the 'hello word' by the current script progress and you're done.
