Have you considered to develop this on the top of chef-server?

I think most features (and more) you mentioned in the video are already covered by the chef-server (recipes, role, ohai, search, provisioning etc), and they have large community and more thoroughly tested.

However, their webui is too simple, and in particularly not extensible - no plugin mechanism so it is difficult to add some minor feature on the top of their webui.

So I think there is a huge market for providing a better UI for chef-server, especially they are one of the leaders in the field?
