look here: http://www.realmcrafter.com/ and your dream will come true with ease, though without fun, without effort and without much thinking and learning.

besides, there's a plugin for 3dgs called PS_HTTP, it supports POST and GET requests. if you think some minutes then you'll possibly remark that you can use em with PHP, and make a PHP script conecting to your webserver while using FTP, download the files there, and you got what you wanted: a filebase server. i know it works, i tried it myself.

u'll need some basic PHP knowledge of course...
