Jason, I guess by "RC" you mean connected mode. The connected mode is now implemented over RC but as was discussed over this list few times, it should (and it would) move to use UC, which is also much easier to implement in hw based gateways. Anyway, your idea to allow this feature coming into play only under negotiation schem sounds fine to me, however: > You may also want to look at using the new TSO/GSO/LRO stuff in a RC > context.
