AFAIK the prequisite for a cluster of any kind (be it RHEL or RAC) is 
that you have a failure-resistant network. This can be achieved for 
example by using dedicated heartbeat switches or cross-cables (in case 
of two nodes), plus ethernet bonding (in linux) for redundancy.

While I understand your requirement, I don't think an environment with 
(possibly) unreliable n/w is a good place for a cluster. Perhaps a 
simple thin client is more appropriate.
