That sounds reasonable.

So this is a bit different to Theodore's setup as you want a static
gatewy. The simplest method is probably to allow dhclient to set the
0.0.0.0/0 default route itself, and add lines like these to hostname.if

!route add 0.0.0.0/1 $gw_address
!route add 128.0.0.0/1 $gw_address

That way dhclient can add and remove addresses as it wants and it
won't interfere with your real gateway. (Some of the tun-based VPN
clients use the same trick).
