Thanks a lot, apparently I'm to blind to see the obvious.

yet (completly off-topic) this segfaults:

int
MultiFlowDispatcher::initialize(ErrorHandler * errh ) {

  int i;
  for (i=0; i<=1; i++){
    if ( input(i).element()->cast("MultiFlowDispatcher") ){


and the debugger tells me that the input has no element

(gdb) p input(0)
$1 = (const Element::Port &) @0x826d324: {_e = 0x0, _port = -1}

are the neighbors not known at initialization time?
Is there anything better than this really ugly thing:

MultiFlowDispatcher::push( ) {
	if (!_neighbor_config)
		do_neighbor_config()
}
