£25 management allowance a 'ceiling' claims leading GP

So yet another thing we don't know - the size of the "management allowance" and what it will cover: I was unaware that it included the costs of "public health and primary care contracting": what else has to be covered before starting work?
We don't know what size will be approved - local, co-terminous with local authority or large enough to cover risk; where the contracts, funding and control of GP systems will lie, with CCGs, NHS CB or elsewhere; what services will be commisioned directly by CCGs and what on a larger scale; who will be in charge of functions such as Performers Lists (these also apply to pharmacists and dentists); Revalidation (and Remediation?) and Registration Authority functions (issuing smart cards and managing RBAC): will these also come out of the management allowance?
Katie Davis told us not to worry about GP systems and what happened after GPSoC ended - number 10 was taking a personal interest: is he alo taking an interest in the other known unknowns?
