In-line editing of attachments through the web browser…

Hey folks, do any of you know of low-cost or free solutions for in-line attachment editors for Notes web based apps? I need for my users to be able to open a Form on the web. Click an attachment, open it, Make edits, and then save it right back to the form in place. No need to delete the old attachment and upload the new one. I know that DLI.Uploader would do the trick, but I’m hoping to find something free, or for less than the $999 price tag that comes with the DLI product. If anyone knows of anything, please let me know. Thanks!

Our servers are on 6.5 and our browsers are IE 5.5 and above. THANKS again.
