I hate to break this to you, but the Definite Guide probably has the best information (including diagrams) out there (that I know of). Because of all the possible permutations of multi-datacenter setups it is going to be difficult to find some doc/presentation that describes EXACTLY what you want to do and how it will work. Here are some hints: You can setup a simulation cluster. Give each host ips such as 127.0.0.1 127.0.0.2 since you do not have to explicitly configure those on a single host. Set the XMX low for each instance. Run in foreground and/or set your logging to verbose so you can debug which nodes data land on.
