If possible, it might be a good idea to allow the RSA's to handle multicast requests also. Having machines join a session via the KBE would be a good way to implement this.
Supporting IGMP (instead of just PGM) would be nice also.
This request has been implemented in the SDA (K2) 4.0 release
The lack of multicast support on the RSA is slowing us down, and the fact that the K2000 only uses PGM for multicast but our Nexus 7000 router and Catalyst 3750 infrastructure do not support this protocol is very disappointing. This definitely slowing us down as we have to rely on unicast and RSAs for our 31 different subnets. Please add RSA multicast support and please definitely add support for other protocols, such as IGMP or PIM. Looking forward to these new features on future K2000 releases.

When do you think the RSA will have multicast capability added as part of the RSA reacrhitecture?
