Interesting... I'd suggest adding a debugging print to factory_success, probably like so: 
sub factory_success {
    my( $handle, $wheel_id ) = @_[ARG0, ARG1];
    $_[HEAP]->{clients}->{ $wheel_id }  =
      POE::Wheel::ReadWrite->new(
        Handle    => $handle,
        Driver    => POE::Driver::SysRW->new(),
        Filter    => POE::Filter::SimpleQueryString->new(),
        InputEvent  => 'client_input',
      );
    print "factory_success called, creating wheel $wheel_id for handle
+ $handle\n";
}

and then add a similar print to client_input.

I don't see any obvious typos in your code or in the article; the perldoc for POE::Wheel::ReadWrite says ARG0 and ARG1 are what you say they are.

(Although the perldoc for the version I have has a whacky example: 

sub input_state {
   my ($heap, $input, $wheel_id) = @_[HEAP, ARG0, ARG1];
   print "Echoing input from wheel $wheel_id: $input\n";
   $heap->{wheel}->put($input);     # Echo it back.
}

Note the use of wheel rather than wheel_id :) )

Wish I could be more help, but the link to the example code in that article is dead, so I can't run a local copy to see if I get the same problems you do.
