Read the article, folks. The software has the liturgy and the readings. (I'd assume it has all the Propers, meaning those parts of the worship service that change based on the day on the liturgical calendar.) That means it has nothing to do with sermon preparation, but instead with preparation of the liturgy (what most lay folks call "the service"). See http://www.vislit.com/articles/intro.html for more info. Poor techie writer didn't understand his subject matter. (A liturgy, for instance, is not "delivered," while a sermon is.) Also, all the (predictable) jokes re: "sermon = virus" reflect the same misunderstanding. (Of course, the Visual Liturgy folks seem to be pitching their software towards folks who don't exactly have a strong grasp of technology, too.)
