Subject Re: Cassandra access control

I also like this feature, I also use keyspaces as another dimension
for some applications.  I also don't worry about "securing" cassandra
as I run behind firewalls.  I can see the argument for authentication
per keyspace, but I like it as optional.

For instance consider the use case where you have are running a chat
server with public rooms and private rooms.  Public rooms live in a
keyspace with no authentication, and private rooms each have their
own keyspace with a token (a bit contrived, but you get the idea hopefully).

Users would have unauthenticated access to one keyspace and authenticated
access to others but be able to query both over the same connection.
