XMLHttpRequest has progress events and you can send files and form data
using it.

I’d like to propose that UAs should surface an bytes transferred event
when a form is being submitted. With so many large files being uploaded
using browsers today and every website that allows this having had to
implement their own upload progress indicator I think the Html 5 spec
should support this very common need.
In Flash player, the FileReference object surfaces multiple events such as
Select
Complete
IO/Error
Progress
Upload Complete - makes available the response from the web server,
which could be displayed to the end user
The progress event provides bytesLoaded and bytesTotal and with this
information one can do the following:
1. Show the user how much time before the file is uploaded completely
(in some cases it takes them 7-8 hours to upload afile)
2. Using this information we can also calculate the rate of transfer
(upload speed).
Ideally UA should:
1. Show the upload progress along with the estimated time left and
upload speed. If this is provided at a control the site developers can
place this control and skin it they way they’d like to, or the statu bar
of the browser should show this information.
2. Allow for filtering the types of files a user can select by providing
a semicolon delimited list of file extensions such as
“**.wmv;*.mp4;**.mov” etc.
At a minimum, I think they should provide a Progress event and
UploadCompleted event.
