I am intrigued. Do you have any quick links on hand, or pointers on how one would go about learning how to set up something like this? Or just learning about how to distribute services in general?

That is to say, I know my way around Linux, have set up single/standalone servers for all sorts of services, but have never known remotely where to begin on the distributed side of things, much less understand what is required to makes something "designed to be multihomed".
