update-policy restricting to a subnet

Is it possible to restrict user machines to only be able to update  
their 'A' records on a specific subnet? We would like to allow DDNS  
but restrict it to specific subnets and only allow the machines to  
update their 'A' records. Allow-updates will not get us the record  
restrictions we would need to implement this and it doesn't appear  
that update-policy has any understanding of subnet scoping.
