Simplest Ajax upload jQuery plugin?

I'm looking to add ajax uploading to my application with a progress bar, but the only solutions I've found seem to be entirely vertically and overly complex. I'll need to do my own styling for basically everything, and I need some c开发者_JAVA技巧ustom functionality, so I'm looking for something simple.

My desired behavior is this:

1.) User can select a number of files.
2.) User hits "upload" and the ajax upload sends each file one at a time, with independent progress bars.

I need an Add Files button essentially, and I'm restricted to NO FLASH. I only need to support latest Firefox and Chrome, so IE8 isn't an issue.

What plugins should I be looking at? Non-GPL licenses are preferred.

Without having ever tried it — http://valums.com/ajax-upload/ seems to do what you want:
