All things related to multicast

[Jeffry Handal <>]

Eldon, at al.

With your feedback about being Apple machines and a colleague here at 
LSU, we found that it may be the very group that Bonjour runs on. We 
checked a machine we have access to and ran iTunes on it with Windows 7 
as its OS. It installs bonjour in the backend. Checking on the command 
prompt with 'netsh int ip show joins,' that machine is requesting to 
join. The mystery may well be solved now...

The difficulties here were: bonjour is not very well document on the 
web; this group does not build the shared multicast tree as other 
software does.

Any way, thank you everyone for their feedback. Feel free to contribute 
on any more insights. This is just an initial educated guess.
