on systems where there are multiple users accessing the same files,for example where more than one person is developing "code", some sort of way to know that a file is currently being edited, say with a mini icon over the actual icon image, or say a RED colored background when selected, need to be implemented.
this can be done with AJAX and a file (or database for multiuser version)
I am currently in need of this functionality for developing an online game.
I will look at creating code that can be used as the basis for v5 clientside plugins that require AJAX or other round robin contact with the server.
