Thanks Larry and Diez. I figured that doing 'GUIs over the web' would probably not work.
Where I work, we have a bunch of numerical weather-prediction-type models that take several hours to run. By having a cron job copy over the output, I think I can still implement a type of progress bar using an update button, and show some png images as well. Animations would be nice, but I have not reached that point yet. In case anyone is interested... The initial plan was to use a GTK+ GUI to monitor these models and the GIMP library to create an indexed image from the pressure field, overlayed with vectors depicting winds (or currents, for the ocean). Think I'll take another look at pygtk. Mike E -- http://mail.python.org/mailman/listinfo/python-list
