If data ingest is local to the master, then it is feasible that the ingest bandwidth is much higher than can be efficiently acheived between e.g. Oregon and Virginia. We would also probably need some sequence function so that while clients reading from the slave might see stale information, they are not at risk of seeing Key combinations that have never existed.

Are you concerned about data being written in a different order on the slave?  Or mutations being broken up?  Or something else?
