Open/Save to server

I have created a plugin and customized file browser that allows for opening and saving directly to the file system that is serving up the editor. Since I had to make a custom file browser, it's only available for PHP at the moment. Question, has anybody done anything like this already? And is anybody interested in something like this? It's close to being finished and if anybody else wants it, I will write up some quickie instructions and package it up.
