There's a few:

    * Qemu installation (for the qemu-img tool that converts to VMWare
    * VirtualBox installation (for the vboxmanage tool that converts to
      VirtualBox disks)
    * The overlay stuff also requires:
          o ability to mount a loopback partition (to modify the ext3
            image with the overlay)
          o ability to do an rsync over top of the mounted image
            (requires super-user access AFAICS)

The first two might be something you could run on dev (though I'd be 
hesitant to increase your attack surface for the machine that way), but 
the overlay operations are not the kind of thing you want running on a 
publicly accessible server AFAICS, just too many security issues, 
really.  You'd want to run it on an old box somewhere with nothing 
sensitive on it and then push the images up to dev I would think.

Enjoy yourself,
