Upload progress bar with Paperclip, Mongrel, Apache

Hello all,
I've been looking now for several days for an easy to use progress bar
plugin or tutorial. I have Paperclip installed and it works great.
My production server runs on Apache and Mongrel.

It's amazing that there's no easy set up progress bar plugin or gem out
there. I have seen "SWFUpload", but that seems very complicated to
implement.

Thank you for any tips or help.
