Sounds like a cron job and a web server.

The Google App Engine tutorial revolves around trying to dynamically create a web site, and I haven't been able to figure out how to make anything other than an index.html file in the root directory work. HOW DO I MAKE OTHER FILES PUBLICLY READABLE?
I don't know Google App Engine, but the normal way to do these things
is to simply drop a file into your web server's designated root - for
instance, /var/www/results.csv would be accessible as
http://yourserver/results.csv - just put it next to index.html. But
you may need to configure it, if it's set to a more secure default
setup that allows only html files.

Here's a possible solution for you. Make your screen.py web-accessible
(maybe with a password or IP address check, if you don't want it
public) as your means of regenerating the file, and create another one
that returns it. You can then have a cron job on any other computer in
the world - your own home box, for instance - that runs:
You can store the csv file as an actual file, or in a database, or
whatever's convenient. You just need the other script to be able to
