</div>Sure it does. A typical home network these days uses ethernet switches,<br>
rather than hubs. The switches are smart, they memorize MAC addresses<br>
and then send traffic only where it needs to go, keeping other ports<br>
free for their own traffic.<br>
<br>
Multicast defeats that, sending all (multicast) traffic to all ports<br>
all of the time. Much, much heavier network load.<br>
<br>
Probably still not a big issue, but the original poster makes a good point.</blockquote><div><br></div><div>That isn't entirely true. Multicast aware switches will only send multicast packets to the hosts that need them. So it comes down to the capabilities of your switch.</div>
