Isn't it moving block on the DLR? Have they got anywhere near getting it
working on the Jubilee yet?

Yes, and Yes - the Jubilee has been using moving block since Christmas,
(it's known as the 'transmission based train control system' (TBTC)) ,
except for the section between Dollis Hill and Stanmore.

The conventional signalling is no longer used, which is why it is all
covered up.
