Meegotouchhome basically:
- shows a _NET_WM_WINDOW_TYPE_DESKTOP window
- provides a way to start programs (I believe it uses D-Bus activation)
- sends the root window a _NET_ACTIVE_WINDOW ClientMessage when the user
wants to switch to a particular (application) window  (e.g. the user
selects a window from the task switcher)

These you need at least to replace it.
