finally had some time today finally and wanted to try the hack,
I tried to find the files on your site
there's no files section listed on the page
search for rally-x failed (Besides a jamma adpater)
search for "files" didn't find anything regarding the hack
so I figured maybe you just put it up but didn't link to it anywhere, so tried directly
http://cambridge.../files
that actually got back a response, but a 0 length response

man I feel so trolled.
figured, maybe it's on an FTP server or something rather that you webserver, so tried anony FTP and was actually a bit surprised to find there was one. but your FTP server hates me.
oddly when using anonymous sometimes it prompted me for a password, sometimes it just said logged in right away which was weird but regardless after logging in connection closed before I could even get a dir, switched to active rather than passive mode was able to get a dir, but there didn't seem to be a files directory just a bunch of .jpg files.
anyway I'l be willing to give it a test in my rally-x if you want to shoot me a link to the image.
