Hi,

We are ciotoflow[0], and while setting up a piratebox[1] we made little
change in your code to add the upload percentage progress.
Only a number is showed now, but can be added something more pretty
likes a bar or something.

We use a wrapper for a file object to know how much data we have
collected, store this on a file. The client made ajax calls to retrieve
the percentage value in that file.

Sometimes somethings goes wrong (maybe because we are writing and
reading to the same file) and an broken pipe exception is rises.
By the way the code works and we will not fix this very soon, so i
prefer send you the code anyway.

I send you the new code and a diff file.
Hope you like it.

Bye.
