As a related issue, it would be nice to have a utility that either dumps
a whole key or a whole keyspace in some format (YAML, XML, whatever)
without access to the machine where Cassandra lives.  I didn't see such
a beast in the repos or any of the tools out there.

There doesn't seem to be a way to get all the keys in a keyspace in the
API (with a random partitioner, the order preserving partitioner can
enumerate the keys).  This would be a problem in writing such a tool,
right?  Or did I miss something?
