192334 AJAX Page Load Script

I need an AJAX page load script similar to Protoload[1] & the AJAX page loading of Plesk 8.x this script must be easy to "plug in" to an existing PHP or HTML page / site. the primary usage will be for "AJAX-ifying" an existing BitTorrent tracker script. it is preferable that the script be based on either Prototype or jQuery. mootools is not an option. you must have existing AJAX work to show. a demo w/ AJAX page loading is preferred. please include demos in your bid, otherwise I cannot select you. thanks. payment is via PayPal upon project completion. project price is negotiable, but must be reasonable. i.e. must correlate directly to the workload & time involved [1] [login to view URL]
