absense of multicast deployment

If there's such a compelling need for native multicast, why has it
seen such limited deployment

It hasn't been needed by enough people

We have a growing need and are doing a little bit to encourage use


Other content owners agree, we have a number working on joining us
(sadly I can't mention names until they're live)

This is a work in progress (it's been live for two weeks), we have a
long way to go.

When I see a need for V6 and it looks viable I'll try and do the
same for it. As it's only doing something we can do already it'll
be a harder sell.
