What kind of router is your customer using?  Cisco routers allow you
to define "secondary" IP addresses in addition to the primary IP
address for an interface.  You could use this feature to configure
your router to have two logical subnets sharing your single physical
subnet. 

Then on the Mac you can configure the Open Transport TCP/IP control
panel to use either the primary or secondary router IP address for the
"router address" field - depending on whether the Mac's IP address
is in the subnet of the primary or secondary router IP address.
