To help illustrate MetaNav, I’ve created two screencasts:

• MetaNav Overview screencast (direct link to full-size version)

• Plone Walk-through of MetaNav screencast (direct link to full-size version)

Briefly, this product allows Plone administrators and content-editors to build and maintain an alternate navigation hierarchy for their site, such as in audience-based and topic-based navigation schemes.
