If I understand correctly, you have a 'mint' node running on a server that's associated with a user ID, so that user's trust record is tightly associated with the reliability of that box. But with MaidSafe, the mint node would exist on the network & redundancy is baked-in, so there's only a user ID involved- the durability of the mint node is effectively forever- or at least for as long as sufficient resources are made available to cover the node's network resource usage.
