It's possible to integrate PowerPoint and Keynote presentations in several ways:
1) Images. This is the safest/most-portable way, where your PPT/Key presentation is exported to a sequence of images that Proclaim imports. This avoids any formatting problems and ensures cross-platform compatibility, even if you import a presentation from one platform and present on another. Negative: You can't get animated builds, point by point reveals, etc.
2) Content import. Proclaim reads PPT/Key presentation and extracts text and images, putting them into its own format. This is likely to increase formatting errors on complex slides, and doesn't bring in transitions/builds, etc., but would work for simple text based slides and make them editable in Proclaim.
3) Shelling out. We can control -- or shell out to -- PowerPoint or Keynote at a certain point in the presentation. Complicated, and possibly a source of UI conflicts / problems, but would allow full featured use of the other products in the middle of a Proclaim presentation.
