Just to update this, I located DU Meter and installed it on my 64 bit Win8 Pro and the software ran fine. I then right clicked on the taskbar and picked the toolbars menu, found DU Meter and ticked it.
Having done this I have DU Meter integrated into the taskbar and Start8 1.1 is running. Having rebooted it remains in place.
Obviously it can only appear on the primary monitor taskbar, but thats a limitation of Windows 8, not Start8.
