I think he's saying that it'd be nice to have a web interface for getting/putting one or two files on machines that can't have the client installed. Dropbox has this.
Installing rsync and uploading a file to Dropbox's web interface are significantly different actions. The install restrictions might not be to prevent offsite transfer of files - it might just be to prevent people from installing AIM and trojan horses.
IT has the machines locked down for a reason.
