Subject Re: Cassandra Demo/Tutorial Applications

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.

Cheers
