Given that you want to use the same domain in the different views, 
then I'd be tempted to run independent instances of both DHCP and DNS 
for each subnet.

Three instances of DNS is fairly easy since you can bind each one to 
a different address on one interface.
You can't do that with DHCP since it needs to receive broadcasts. 
With some restrictions I think you can make ISC DHCP do it - but you 
need to recompile it with different options set (dunno what, but they 
prevent it directly dealing with packets on the interface) AND all 
requests must come from remote networks via a relay agent set to 
unicast the requests to the server.
