I think this is a bad idea for him....like he said on the original post is he's trying to keep it clean. With this tool/utility that will just open up for lots of un-needed files like Beta versions etc., etc..
Admins should verify that stuff before making a map available on the server anyway!
Yes it's a cool tool/utility but...
That's why the uploads should be done on a different directory than the redirect. ...So it can be examined for junk. Also some one could offer to code a script to filter out any file other than a *uz3 files to automate the process.
EDIT: In addition "redirect server checkers" doesn't upload system, private, and text files. Like I saw people do on "gameserver." manually. They would take a complete directory and compress it an ftp it up to the redirect.
