Depending on how much data you require back, if it's just a simple
status report then you can invoke a http header from your server side
script,
e.g
In an application for image uploading, I needed response back along
the lines of
a) is this image cmyk or rgb
b) does this image dpi = 300
c) is the aspect ratio correct
...
etc

For each state, I output a header using rarely used http errors e.g
from 408 through to 417
then caught them from the fileReference onHTTPError event. I posted
some stuff on adobe livedocs about this a while back though can't
remember the url.

You could also write data to a database /session from your initial
upload process, then make a secondary loadvars call onLoadComplete to
another script that then accesses this data. There are things that can
be done via xml sockets as well but thats probably overkill for this.
