By the way, the next CJO has been announced as being the current CDI, AM Peach (Navigator)
Peach is undoubtedly one of the stars of the current firmament, a very capable operator who understands his stuff and doesn't take too many prisoners.
Do his dates as CJO co-incide with Stirrat's extension to 2011? Maybe there is a current candidate for next CDS - although I'm sure back-back light blue would cause a few harrumphs amongst the other services.
