You would need a multicast-aware switch. The Cisco 2924 series aren't
that nice. I have no idea about the 3com switches. I think any Cisco
running CatOS will work fine.

My 6509 works fine and my Lucent P334T works like a charm. You need a
switch that does is "Multicast aware" and performs "IGMP snooping". So,
just read the technical specification on the switch.

Lucent P334T's are nice we have a few. I don't think we paid more than
$1000 for any one of them.
