All, Vik's feature would be useful for detecting an accidental split in a replication cluster. That is, it would be another tool for detecting if you've made a mistake and created two masters. So +1 from me.
It will also be useful for me for sharding. Right now, I'm doing a hackish version of Vik's function, so I'd be glad to have it in core. However, given that the value is the same for all servers in a replication set, are we sure we want to call it system_identifier?
