The real solution here is to use ip aliases. If you have the debian kernel
image installed (and are not using a custom one) it is sufficient to use
the ip_alias module

Let's assume a free IP adresss on your friend's subnet is
with netmask then the following will do what you want:

# modprobe ip_alias
# ifconfig eth0:0 netmask broadcast
# route add -net

There is no need to do something on the other side.
