That sort of overhead's resultant latency would destroy the performance of a cluster on all but the very fastest of machines. Ah, right, I'm forgetting that clustering sends a lot of data. Yes, and it's all pretty latency-sensitive. Further, most VMS clusters are built with machines in the same datacenter. It's not generally a wide-area thing. Mmmm, true. Clustering is generally used for practical purposes and not my crazy experiments. Right. And the VMS world isn't generally too worried about cracker kiddiez and their rootkits. Now, if you manage to bring up a wide-area cluster (which I'd love to see!), of course you could encrypt your tunnels. (I would) -Dave -- Dave McGuire, AK4HZ New Kensington, PA
