I have just tried it again with Xinerama off and using twin view. I've got
something but still not 100% there. I now get a separate DE/WM session per
monitor. RandR does work but running it in any of the three sessions, it
can only see it's respective monitor.

Im going to RTFM a bit here and do some googlefu, as I've made progress.
Cheers.

Simon.
