I'm very interested in ragtek's article system as well.
Also, I was not aware a working Joomla integration exists. I'll have to research that.
But workflows are just one of the requirements we have.
Multipage articles are needed as vertical scrolling is only acceptable up to a point.
We will also need the ability to create several content types each having different fields.
For example, articles must require a default image associated with that article.
Other images can, and usually do, appear in the article but each article must have a default image that is used in the layout in the top right of the article, and also appears in the articles summary page (with the other articles) with a brief description of the article.
Another example would be the overview field. This is a summary or highlights field that is displayed as the teaser. We've tried in the past to use the first x characters from the article but it works best to have a separate teaser field.
Regarding creating content types, here are a few we need.
For articles, we will need the fields default image, overview, article, and author info.
For the Who's Who content type we will need the fields default image, overview, and article.
For the Best Sites content type we will need the fields Site Name, URL, overview, and description.
There are others as well but they are similar to these.
