OK, given your assertion's, HOW is machine B supposed to send data to
my machine?

       
Ethernet =
SLIP/PPP *

              machine-A<=>machine-B<=>machine-C<*>{internet}
                  ^
                  *
                  v
             Nate's box

I have two options, and I chose the latter since it's much easier to
setup because we have other boxes also sitting off the machines in the
network.

1) Have machine A arp for my IP address.
2) Have machine A declare itself a router from my IP address

With your assumption, machine B does is not running any routing
software, so therefore it does not know to send packets to machine A in
order to get to my machine.  Note, there are many machines similar to
machine B in my network, and I'm not about to add static routes to every
one of them to force routing to my machine.
