Looking for a pre-built CI solution for web site template hosting

[eluser]Myles Wakeham[/eluser]
Just curious... We have a number of clients that want a simple few page website built that they can manage simply (something like what SquareSpace offer) but I'd like to have this as a service on our hosted servers that we can extend to them so they can do their own simple web pages, etc.

Does anyone know of a CMS that is really simple for non-techies to use that is written in CI that we might be able to offer them?
