DHCP - Multiple Scopes

I have a straight class C network 10.200.1.X 255.255.255.0 with a single DHCP
server/scope serving clients on the local subnet as well as remote VPN users
dialing in through RRAS. I am dangerously low on IP addresses and need a way
to either A) create a second DHCP scope (10.200.2.X) specifically for the
mobile VPN users while still allowing them to continue accessing resources on
the other local subnet (10.200.1.X) as before or B) setup the second subnet
under a superscope and allow all clients to pull from either address scope.
I have considered the options of using the RRAS server as a router or
possibly just setting up a superscope. Any suggestions and examples would be
greatly appreciated.

No superscopes. Those are only for Multi-Nets and there is no reason for
that here.

Just create a new subnet on the LAN. Tie them together with a LAN Router
(Cisco, RRAS, HP, whatever). Add a *normal* Scope to the DHCP Server for
the new subnet. The router forwards the queries to the DHCP from the new
subnet. Simple, clean, no uneeded complexities,...and when it gives you
problems you'll actually be able to figure it out ;-).

Extra note: It is a good idea (no, a great idea) to keep subnets below
250-300 hosts. This is best accomplished with a standard 24bit mask and it
is certainly easier to keep track of than if you start "borrowing bits" from
here and there. Stick with the 24bit mask (255.255.255.0)

You could simply use a static pool of addresses for the remote users and
let the LAN clients use the full DHCP scope.
