I had filed this with my SE as a feature request, and while he'd  
initially thought it would  be in Leopard, the last time I asked  
(last fall) he told me it had been pushed back.  It wasn't clear if  
it had been removed from the Leopard road map, or just hadn't made it  
into the current beta at the time.

I haven't checked the latest beta to see if things have moved forward  
from what he'd told me then.  You sign an NDA to get on the beta, so  
I can't really talk about it even after I do check it... which is why  
I'm reporting what I was told, not what I might have tested on the  
earlier betas.

I may have to give in and install a linux partition in parallels to  
do IGMPv3 testing of switches.
