It really depends on how you're fetching the data. If you write your own
method to read a few kilobytes at a time, you can easily update a status
bar. Otherwise if you know the file it's downloading to (i.e. not a temp
file) you could continually call os.stat to update the status bar
(especially if you know the size it's supposed to be in the end).

HTH,
