Per Jun and my conversation with Cliff Moon at the hackathon, this is not 
something we want to pursue in Cassandra.

> Writes to a row today can be run on any of the replicas that own the row. An 
> additional set of APIs to perform "mastered" writes that funnel through a 
> primary is important if applications have some operations that require higher 
> consistency. Test-and-set is an example of one such operation that requires a 
> higher consistency guarantee.
> To stay true to Cassandra's performance goals, this should be done in a way 
> that does not compromise performance for apps that can deal with lower 
> consistency and never use these APIs. That said, an app that mixes higher 
> consistency calls with lower consistency calls should be careful that they 
> don't operate on the same data.
