1. i usually do, i just wrote that more as the 'beta'.
2. already done. see code below.

use strict;
use IO::Socket;
use IO::Select;

my $listen = IO::Socket::INET->new(Proto => 'tcp',
                   LocalPort => 9192,
                   Listen => 1,
                   Reuse => 1) or die $!;

my $select = IO::Select->new($listen);

my @ready;
while(@ready = $select->can_read) {
    my $socket;
    for $socket (@ready) {

    if($socket == $listen) {
        my $new = $listen->accept;
        $select->add($new);
        print $new->fileno . ": connected\n";
    } else {
        my $line="";
        $socket->recv($line,80);
        if($line eq "") {
        print $socket->fileno . ": disconnected\n";
        $select->remove($socket);
        $socket->close;
        };
        my $socket;
        for $socket ($select->handles) {
        next if($socket==$listen);
        $socket->send($line) or do {
            print $socket->fileno . ": disconnected\n";        
            $select->remove($socket);
            $socket->close;
        };
        }
    }
    }
