Sure :-)

* squid runs at X.X.5.76
* wccp2 runs at C2800 with multiple addresses, X.X.5.66
  and X.X.78.241 among them
* X.X.5.66 is in the same subnet with squid, so we send
  wccp2 notifications from squid there
* X.X.78.241 gets chosen by IOS as Router Identifier, so
  we have to configure it as the gre tunnel remote endpoint
* 172.X.X.X are deliberately non-existent, they are just
  place holders
