You can run IP via PPP. PPPD is used all the time for VPN. I've got 2 networks that are combined via PPPD over a tunnel because they are both on private networks and have only 1 public IP. However, The overhead could get you. I'm not sure you want to go down the writer of creating another interface. Maybe you could use the SLIP interface and capture that IP stuff and send across.
