Hi Joe, we have a user who originally wanted her child site to be based on WordPress (I think mostly because that's what she's familiar with). After we demoed mojoPortal for her, she agreed that it would work for her needs as well. However, she is still not fully satisfied with mojoPortal's slideshow feature. What she really wants is an enhancement that will allow moving around manually within the slideshow elements.
The example slideshow sites she sent me are: The San Francisco Public Library (clickable numbers for each element) and the Washington D.C. Public Library (thumbnail images for each element).
On a semi-related note, I think it would be most awesome if you could enhance feed manager to include a slideshow of elements display mode.
As always, thanks for your attention!
