The processes would talk to each other, but things would just go to pieces at the point where openvpn starts trying to interact with the local routing table. If you're interested in experimenting with openvpn, I would suggest looking into one of the many virtualization options such as qvm/kemu, virtualbox or vmware-server. With one of these, you could have 2 or more hosts that you could configure to act as servers and/or clients.
