I read Kiln People a few years ago, but since I work about 10 feet from a library sci-fi collection I am constantly reminded of the book.  It is a very interesting book on what it means to be you and what it means when there are copies of you running around. And also deals with what a society would be like if you could have temporary "Ditto" copies of yourself. 

The whole concept of how society deals with technology is very interesting to me.  Moreover, Kiln People is an interesting re-interpretation of some of the concepts that Aldous Huxley brought up in BRAVE NEW WORLD about class in terms of clones.  Clones of yourself than you make at home are color coded. A cheap ditto suitable for housework is green, whereas a quality one for business is gray. Ebonies are highly specialized dittos that are good at intelligent data analysis; platinums are only used by the very rich, and closely resemble real people.  The interesting question is, “Are you exploiting yourself when you clone a 'simple version of yourself?"  In Brave New World the concept of a 'Delta' seems exploitive to the reader...someone born to do menial jobs...but what if you make a copy of yourself to do ‘your own’ menial jobs?

The whole book is full of interesting ideas about "selfhood" and the society that would develop around cheaply made temporary clones.
