The faq mentions there are no security features at the moment, but do you have any thoughts as to what the security goals are? In particular, will there be cell level security a la accumulo or support for data at rest?
My guess is that the first pass will be table and column level authorization, plus of course strong authentication. Row/cell/predicate-based security could be added in a later release, but it's a feature that's less commonly required.
As for encryption at rest, I imagine that will also be fairly high priority as we move towards GA or the first few releases after GA. But again, we haven't done the scoping exercise yet, so I'm cautious to throw out dates :)
