Absolutely. Normally these ideas are used in a live presenter-to-audience context, but Relational Presentation works exceptionally well as a content management strategy, especially if you have a lot of pictures and other media. Some companies are starting to build parts, or all, of their intranets based on this approach rather than an html structure, due to the ease of creating and modifying content. 

Portability is another issue. When an intranet is PowerPoint-based, you easily can transfer a chunk of it to any computer and be ready to present in a live context. We've seen people arranging their content in clusters so that entire categories of information are basically "plug and play." In other words, a presenter just plugs a module of content into his or her network when needed.
