All things related to multicast

[debbie fligor <>]

So I've got a feature request in at Apple for IGMPv3 support, and 
they'd like to know what Mac users wont be able to do if we don't 
have that support.  I'm not that up on what's out there SSM-wise, can 
those of you that know what's available now, and what's in the 
pipeline that is SSM based help me out here?

any other useful points I should make? does having an IGMPv2 speaker 
using multicast on the same subnet as IGMPv3 speakers cause issues, 
problems (I vaguely recall that the local switch might back out to 
v2, but I'm not sure if that's only for the one host or for 
everything...).

thanks for any help you can provide!
