I was referring to my code, not your code d8)

| they are two distinctive part to do that:
| 1/the client side, wich gets asynchronous feedback from the server, that

| 2/ the server side that keep track of a given request state. (getting
| data / processing)

No, I didn't. There's only one CGI to handle the upload. The rest is inside
the Zope Product, which tracks the state of each upload. You can call
http://example.com/path/UploadManager/uploadId/percentComplete
and get a number from 0.0 to 100.0. There's also methods to get error messages etc.

I'm just too lazy to write a nifty front-end to it d8) I'm sure someone else 
will and I can just add that to the codebase...

A few people have expressed interest in it, so I'll get it scrubbed up and
released. At least the next time someone asks, there's somewhere to point them
to d8)
