Open Stack

Hey everyone!

Try-it vs. Very-complex:
Separate projects, with links to eachother in the READMEs.

Production:
I use my chef recipes in production.  Some more organizing and some
re-thinking has to go into them to work well.  I'd like to start that
conversation in another thread, after taking a second look at where other
folks have gone with the Swift recipes.

I'd reference again my blue-sky blog entries from last summer on Swift and
Chef.  I still run my cluster that way, but what I've learned since then
needs to be integrated.  Patches welcome!
