Any example code of using hscassandra package would really help!

I'll ask my student.  We may have some simple examples.

Also, I have no idea as to their quality but I was pleasantly surprised to find three different amazon related packages on Hackage (simply by searching for the word "Amazon" in the package list).  

   http://hackage.haskell.org/package/hS3
   http://hackage.haskell.org/package/hSimpleDB
   http://hackage.haskell.org/package/aws

It would be great to know if these work.
