I wouldn't say that. It was way more hassle administering a DB.

It could happen even if the node has backup, since in the worst case the backup server could also failed, and we didn't provide facility for re-assigning a backup node with a running node. 

I believe you don't need to do any syncs when adding new nodes.. but I will wait for Tim Fox (the project lead) to answer that question if you don't mind. He's the wizard on this module.. and I don't want to give you a wrong answer.
