+
+   - SSM: support for source-specific multicast
+     requires: NETWORK_PARTIITONS
+     also requires platform support; SSM is silently disabled if the
+     platform doesn't support it
+
+   - BANDWIDTH_LIMITING: transmit-side bandwidth limiting
+     requires: NETWORK_CHANNELS (for now, anyway)
+
+   - IPV6: support for IPV6
+     requires: platform support (which itself is not part of DDSI)
+
+   - NETWORK_PARTITIONS: support for multiple network partitions
+
+   - NETWORK_CHANNELS: support for multiple network channels
