Andrea:
I see. That is a cool idea, but you are right, concurrency could
definitely be a problem. That's what APC is supposed to solve because
it tags the file with a unique ID. But I can't get that sucker to
return the value to me! If I could get APC to work I would be done.
I also started looking at trying to grab the temp file, ".
$_FILES['video_file']['tmp_name'], and then keep checking its size on
the server, but I don't think I can get the temp name from php until
it is uploaded. Do you know if that is possible?
One other thing, I looked at a canned media management web app ($875
US) that will do this uploading, and it doesn't require APC, so there
definitely is some way to do this with basic PHP.
Thanks, Phred

The concept of my last link is this:
the instant before you do the upload you ask PHP to scan the tmp
folder, or the folder used to upload files (often the tmp) and you
snap number of files, then the upload starts, and it will create a
temp file with a PHP predefined prefix, you array_diff the snap with
the current file list and you get the file that the user is uploading.
At that point if you are lucky the input="file" field will give you
access to its fileSize, and you have everything to create a progress
bar: the polled incremental tmp file size in the server, plus the
total in the client, a bit of transitions/effects and that's it.
This method is not ideal, generally speaking, because it could
easily suffer concurrency between multiple users.
I did not know Flash player had to put the entire file in memory, it
sounds truly silly for scalability reasons, are you absolutely sure
about this?
About APC you need to enable it and so far I had no problems with
files up to 350 Mb , I wonder why 1Gb should be a problem.

Thanks Tom, for weighing in.
Having js poll a script on the server is kind of what APC was about,
and perl as well. Are you saying I could use PHP on the server side
to
do this? It seems almost obvious, but no one mentions it any where on
the web, so a expected there was some fundamental limitation without
APC.
Do you have any idea what this script might look like? Is it possible
to get the temp file name before the upload is completed so that its
size can be monitored?
If it is, it is just too dang simple! ...but I'd take it for sure.
Thanks, Phred
