large file upload

Great question. I too would like to know a good way to handle this.

Is there an existing flash component (or java applet) that could be
used
on a web page to do the uploading (ftp re http) ...and show a nice
percent complete status?

You wouldn't want the upload to quit at half of the 200 MB because the
user accidentally did a browser "back", so any tool would have to have
some javascript to help stop from moving from that page.

Talk about timing, I just stumbled onto an article in "Web Designer"
Magazine (from the UK) issue 139, page 44 where Simon Bailey has a
tutorial on creating a Flex based Flash File Upload tool. It has
features like percent complete and file size limits for uploading.
