Check out the Event module. I've had pretty good luck using it for this type of thing.

# untested, almost verbatum from working code.
use Event;
use IO::Socket;
my @peers;
my $sock = IO::Socket::INET->new(Listen=>5,LocalPort=>8001,Reuse=>1)
  or die "[Fatal] no getum socket!\n";
Event->io(
  fd=>$sock;
  cb=>sub {
    my $e = shift;
    my $h = $e->w->fd;
    my $peer = $h->accept;
    push @peers, $peer;
    $peer->autoflush;
    Event->io(
      # todo:  data => '<peername>' or such to id peers.
      fd=>$peer,
      cb=>sub {
        my $e=shift;
        my $h=$e->w->fd;
        # todo:  my $name=$e->w->data;
        my $line = <$h>;
        foreach (@peers) { $_->print "$line" } # from $name...
        if ($line =~ /^quit/i or eof($h)) {
          $e->w->cancel();  # todo: remove self from @peers
        }
      }
    );
  }
);

Event::loop();

There's much more in the module, io (r/w/e), signal, timer, idle, var (r/w) handlers...
