here's the thing, though, and this is a main reason why cassandra
keeps things simple: doing work on the client typically results in
*less* load on the server.

I think this is a non-starter.  It's pretty clear that the way forward
is towards more programmatic apis, not clients translating their
requests to strings which the server then parses.
