Installing RAC without private network

I am testing Oracle9i RAC on two Linux machines (AS 2.1). Can I proceed with installation of RAC without having a private network (Only one Ethernet card per machine). I know the speed will be very slow. But i just want to test it. We have public network speed of 100 mbps.
I don't have much experience with RAC. But I do know that RAC implements a technology Oracle is calling Cache Fusion whereby each instance's buffer cache can transmit blocks to the other buffer cache. This is typically done through the Interconnect between the nodes. However, it is possible in Linux to have the Interconnect be nothing more than dedicated NIC cards attached with a cross over cable. Since this is possible, I don't see a reason why you can just use your normal network as well. After all, you'll just be setting up IP numbers anyway.
