Thanks Guys for the response. Agreed, I won't be able to do all for my talk - in fact I might defer a lot of hands-on Cassandra to Eric's PM session.
My question on multiple machines and EC2 was more for Cassandra-873 where we want to have a set of good hands-on tutorials; while much simpler than actual production systems, still capture the essentials of a Cassandra infrastructure. And this also can be a homework for the attendees.
