Lots ! There are people with thousands of subnets and/or many 10's of 
thousands of addresses.

I believe so. There is no reasons for it not to.

Yes, for locally attached networks it determines the subnet by the 
interface the packet was received on, for remote subnets (ie using 
DHCP relay agent on remote network) then it doesn't matter. All you 
need to do is define the subnets.
