Sorry have been travelling all last week!

Yes, this is certainly something we should strive for.

Agreed.

The partition a node is part of could be one such piece of information. Whether a node is clustered at all could be another since if it's not, there is no point in assuming a peer could be the same as "this" node.

We should certainly revisit this for JBM 2.0.

Current server peer id is also used to key message data in the database as well as transactions on the client side, so the id needs to be permanent for the lifetime of the data. This is one of the reasons we can't just use something like a hostname, ip address, partition name combination since these might change.

One possibility we would be to generate a string GUID representing the node id when a new node is deployed. This then gets automatically written into the config file and stays with it permanently.
