---------------------------------------

If you can have long strings as part of the unique NodeID, a persisted UUID is an easy solution.

> It shouldn't be needed to assign the node-id manually IMO.
> You could store the node-id on a file and recover it for subsequent starts.
> On hornetQ for instance, we look for the nodeID on a file, if the file doesn't exist we assign a UUID and write to the file.
> In our previous experience UUID would be a best fit to assign the nodes since that was the only way we could guarantee unique IDs between the nodes.
