"My over riding concern is that more talk will mean more delay and more delay will inevitably worsen Silbury's condition."

I understand what you are saying Peter, but I really think there are two agenda's here which is why we have seen such an innordinate delay already. I do not think those two agenda's have been resolved and this latest proposal is a fudge to try to appease both. That being potentially the case, it does not bode wel for the solution no matter how quickly they implemented it.
