Hi Jeff,

We have a handful of VS2005 visualizers for boost types.  Here's what we 
use for boost::optional.  Try plugging this into the [Visualizers] 
section of your autoexp.dat and see if it is the kind of thing you are 
looking for:

boost::optional<*>{
   preview
   (
     #if( !$c.m_initialized )
     (
       #( "Uninitialized" )
     )
     #else
     (
       #( *($T1*)&$c.m_storage.dummy_.data[0] )
     )
   )
}

I am using VS2005 SP1 in case it makes a difference (I can't remember if 
SP1 altered the debug visualizer stuff or not).

    #if( !$c.m_initialized )
    (
      #( "Uninitialized" )
    )
    #else

      #( *($T1*)&$c.m_storage.dummy_.data[0] )
    )
  )
}
