Yes I did it

I rewrote the virtual file system explorer from scratch. It is fast enough and is behaving well. I guess I can add it right now to XPontus XML Editor. I didn't want to copy too much existing interfaces and to borrow code here and there.

Features

• Browse FTP, SAMBA, SFTP and Webdav file systems. You can select http files but you can't browse directories even if direct listing is allowed.
• It behaves almost like JFileChooser

What's missing

• There is no connection manager to add specific settings like proxy
• The username and password are shown is the directory list of files
• There is no details view
  
• There is no real caching of files
• Drag and drop is not supported
• I need to patch commons vfs to support redirects
