Hi Marshall,
BTW sorry if the last mail sounded like I was having a go... I wasn't...
just had one beer to many to be answering mails ;)

PS is this a “geek” group and should be subjecting people to this?
I don't know about the Geek ratio of this group... I guess we'll find
out.
SSM is cool, but it is not necessary to source content. I would not
hold up anything for that.
Doing multicast is not really that hard, anyway. If you want, we can do
it for you :)
I agree, ssm is not necessary at all, especially in the enterprise where
you have the whole of 239/8 to use. Again its not hard either... (well
actually when you start doing it with non Cisco kit that doesn't have a
protocol like CGMP and you use IGMP snooping on the LAN it becomes more
of a task) but I presume you are talking about in the enterprise? Again
it's not that hard in the service provider network but you have a few
more issues than just technical ones to over come and when you start
looking at implementing it with multi vendors platforms it becomes
harder still.
If you were talking about on the net is there any point in doing it? As
I don't know a single ISP that runs PIM down to the CPE? Or am I just
well out of date on this one?
Most of our users are either corporate or on Internet 2.
But I wasn't really referring to that my gripe is more with GLOP and the
way an AS only gets /24 of multicast groups and how IGMPv2 does not
allow you to join/leave on the S,G but only on *,G.
BGMP is more or less dead in the water. (I'm part of the IETF working
group.) It may
be available for IPv6, but will never be for IPv4. If you wait for it,
you'll be waiting a long
time.
Yeah I see the list has been quiet for a while now... oh well guess we
have to stick with what we have.
What was my point? Oh I remember the thing you were saying about the
content... that’s what I disagree with... If content owners/providers
*could* multicast there content I think they would... and if me a user
sat at home on my cable modem could watch multicast content.. I would!
It would be interesting to see how many people could pass your multicast
test @ http://www.multicasttech.com/mt/ Im guessing less than 5% of the
people on this list and most of them work for technical organisations.
Cheers,
Nick
