I came across a mention to iA Presenter on iA's website.1 The iA Presenter app seems to be an incoming offering to "create dramatically faster presentations, and deliver them without the usual anxiety."
There's a Twitter account at @iAPresenter (and another one at @iASpeaker).
iA, which stands for Information Architects, is the company behind the amazing iA Writer, "the original focus writing app." ↩
