Minimal install of TDE

I'm about to start on making a live version of a minimal install of TDE for Cobber (Australasian Debian). I am wondering what are the absolute minimum packages required for a working TDE without applications. The intent behind the minimal install is to allow end users who want to choose the applications in their install to install only what they need and want. I will provide synaptic (or a TDE equivalent) for those who want a gui for package selection but there will be no office suite, games, graphics tools, music or video tools. In other words all I want is the visible desktop, menu etc so that the user can navigate enough to install more applications through their internet connection using either synaptic or a terminal. Cheers. Michael.
