I disagree - OpenStack scales down perfectly to two-machine or even (one-machine) deployments (if you don't want HA).

It is a pain to configure, but that's the price you pay for flexibility, future-proofing (scalability) and its' true community development model.

"Pain to configure" is a blocker here, though. That's why we sacrifice flexibility for simplicity. OpenStack is great for environments that need it - VirtKick won't fit them.
