[mod_python] File upload progress indicator

I'm developing an application using mod_python and I'd like to include 
file upload progress indication.. However, I don't see any obvious way 
on how do to such a thing.

It's possible in mod_perl, and I've done it before, using 
Apache::Request (see http://httpd.apache.org/apreq/Apache-Request.html)

Is this functionality possible in the current incarnation of mod_python 
or should I write this component in mod_perl or C?
