Thanks a lot for your help, this is exactly what I was looking for.

Sorry, but I don't understand your answer here, because in my example
there was no rest at all.
However, the solution you posted had a small mistake (a missing \new
Staff), so I send here the corrected version for the mail archive.

Thanks for your help!

%% Start of code: Polymetric notation with Group bars on and off.

\version "2.11.48"

\layout {
       \context {
         \Score
         \remove "Timing_translator"
         \remove "Default_bar_line_engraver"
       }
       \context {
               \StaffGroup
               % \remove "Span_bar_engraver"
       }
               \context {
         \Staff
         \consists "Timing_translator"
         \consists "Default_bar_line_engraver"
       }
     }

     % Now each staff has its own time signature.

     \relative c' <<
     \new StaffGroup <<
      \override StaffGroup.SpanBar #'stencil = ##f
     \new Staff
      { \time 3/4
         d c c |
         c c c |
         d c c |
         c c c |
         c8
       }
       \new Staff {
         \time 2/4
         c4 c |
         c c |
         c c |
         \revert  StaffGroup.SpanBar #'stencil
         c4 c |
         \override StaffGroup.SpanBar #'stencil = ##f
         c c |
         c c |
          \revert  StaffGroup.SpanBar #'stencil
         c8
         %\override StaffGroup.SpanBar #'stencil = ##f
       }
       \new Staff {
         \time 3/8
         c4. |
         c8 c c |
         c4. |
         c8 c c |

       }
       \new PianoStaff <<
            \new Staff { \time 6/8
            c2. |
            c |
            c2. |
            c |
            c8}
            \new Staff { \time 6/8
            c2. |
