Beamer Presentation: Sneak in slides for each bulleted element

Question

So, I am doing a presentation using Beamer.

In my earlier presentation, I used the list elements auto unhiding one each time. : http://www.slideshare.net/scorpion032/building-pluggable-web-applications-using-django/38

using the following code:

\begin{frame}
    \begin{itemize}[<+-| alert@+>]                  \item
        Admin Interface                         \item
        Generic Views                           \item
        Testing Tools                           \item
        Sessions                                \item
        Authentication                          \item
        Caching                                 \item
        Internationalization                    \item
        RSS                                     \item
        CSRF protection                         \item
        File Storage                            
    \end{itemize}
    \end{frame}

What I want right now, is the ability to sneak-in a few slides for each of these entries. Is there a simple direct easy way to do it?

Or should I consider using sections and displaying section titles? The problem with that approach is that, there will be way too many sections and given that I am displaying the sections on top bar, there might not be enough space for that.

Also, how do I display the contents page, with the current section highlighted for each section.

Not sure of the first part, but this may help for "how do I display the contents page, with the current section highlighted for each section"

\AtBeginSection[]
{
  \frame<handout:0>
  {
    \frametitle{Agenda}
    \tableofcontents[currentsection,hideothersubsections]
  }
}
