My only real issues would have been protecting the CMS from the "idiot syndrome" or the non techie who has access to it.

Because, in case some people arent aware, the non techie whilst initially scared will start "playing" - which can lead to disastrous problems - such as using a wysiwyg editor and them playing with the source and removing tags, or closing them improperly - they click save and voila - a mess to be cleaned up
