This is just a modification of the Interlude macro 
http://randomdeterminism.wordpress.com/2009/10/21/creating-a-style-file-in-context/

\def\Interlude{\dowithpargument\doInterlude}

\def\doInterlude#1%
   {\page
     \null
     \vfill \vfill
    \startalignment[center]
      \let\\\crlf
      \interludefont
        \setupinterlinespace[big]
       #1
       \endgraf
   \stopalignment
    \vfill \vfill \vfill
    \page}


But this is ad-hoc. To integrate this with all styles, this macro 
should have its own background and the user should be able to configure 
the font, alignment, color, etc using a proper interface. So, that will 
have to wait until Thomas and I have more time (basically, the end of 
semester). However, as a stop-gap measure, the above should work. Just 
translate

>>      <li class="slide title">
>>        <h1>Test Slide Show</h1>
>>      </li>

to

 	\Interlude{Test Slide Show}
