No need for the client.
There are three scripts total. DPAD.php (main page), upload.php and download.php. It also uses a directory called /uploads/ for temp files and holding the server side strain.
All we would have to do is upload the scripts, make the directory, and let it run. Mine is running on windows, but I dont see why it shouldnt work on linux (thats how i develop for my other clients. Dev on my windows box and upload to permanent linux box.)

As for future developement, I can do the testing on my computer before uploading, so I can make sure it works.
