I think you nailed it.

Sure, I'll buy that.
I can't think of any standalone projects for that, but "compute a
twissandra tag cloud" would be pretty cool. (Might need to write a
twissandra bot to load stuff in to make an interesting cloud. :)

I'd probably go with "virtualbox images" as being simpler for people
who don't have an AWS key already. (VB can read vmware player images,
i think. But there is no free vmware for OS X, so you'd want to check
that before going w/ vmware format.)
Or just have people d/l cassandra and a configuration xml. Probably
easier than teaching people to use virtualbox who haven't before.

You're not going to have time to teach cluster management. Keep it to 1.
