I addressed this in my previous mail.

Well... we do use multicast a bit. We can indeed allocate IPs for you,
out of our AS-allocated range. However, Switches/routers handle
multicast traffic specially, have group/port membership limits for them
and we've also found several bugs. So before you start using it heavily,
I'd like to know what for. :) With only 2 servers communicating, would
unicast not be a better idea?

Let me know,
