[mod_python] File upload progress indicator

Brian,

The problem isn't with file uploading in general, I want to generate 
near-realtime progress indications of the file upload's progress.  Which 
should be possible by examining the Content-length header and making a 
separate connection to the webserver, tracked via a session cookie.  
It's actually really nice to be able to do this asynchronously in Flash 
5.0+ using XML sockets, which I may or may not end up doing.  I'll 
probably open source this component of it since it's really quite 
useful, given that the status bars in IE don't tell you the progress of 
a file upload, only if it's still going or not (and even then, not very 
obviously).

The problem is that when you use FieldStorage, you have already 
processed the file upload.  You don't get callbacks when apache is 
reading.

My client is going to be dealing with large files quite often, and 
although I didn't specify that I was going to provide them this advanced 
functionality, I would like to give it to them anyway as it's really 
nice from a UI standpoint.
