Surprisingly, this situation is not a problem at all for visually interactive presenters, even if they do not know how to remodel the presentation materials themselves. A designer back at the office can make changes and transfer an entire module via e-mail or FTP to the presenters. He or she then simply replaces the old material with the new, and all the links work beautifully.

This kind of marvelous plug-and-play flexibility helps companies and organizations maintain a high degree of central control and quality in the network design, without sacrificing presenter freedom to request changes, even at the last minute.
