No offense, but my suggestion here is that you write up a preliminary list
of your own answers based on your own reading of the doc, specs, and white
papers (and source code) and post that list, like on Google Docs, for
people to review in bulk, rather than force all Cassandra users on this
list to participate in a full security review one item at a time. To
reiterate, you should be treating the doc as the definitive guide to what
is supported - given the importance that the Cassandra and DSE developers
placed on security features over the past couple of years, it really is
truly safe to say that if it isn't in the doc then it is definitively not
supported. Yes, it would be good to review your final list as a courtesy
check, but asking us to confirm what appears to be obvious (i.e., it is not
in the doc) seems more than a bit excessive to me.

If there is any true confusion in the doc, of course let us know (or email
to, but there is no need for us to confirm that you did
not find something in the doc.
