The solution I would like to consider is configuring a list of static peer addresses without multicast. To that end I would like to evaluate HJ's patch for using TCP. It is not one cluster admin that I would have to train, but a potential large number of customers for a product. From the customer's prospective my product will already introduce an "extra" floating regular IP. If we ask for a multicast address and port as well I fear the product may be perceived as too complex, particularly for a customer that intends to deploy a large number of small clusters. Alan
