Cisco Service Control Engine 3.6 software

Well this is not really new but i thought it could be interesting. There is new software for Cisco Service Control Engine. Software version is 3.6. Here are the release notes. What did we see as a biggest change and what are customers asking us. Support for Gx and Gy interfaces for sure. For the first time Cisco SCE supports not only SCE API or SCE Sniffer but also Gx and Gy interfaces. Configuration wise it does not change awfull lot because its just another interface, however challenges could be in integration with PCRF policy managers because everything is still fresh. And off course there are still the old considerations like packages definition, implementation of Fair Usage Policies, and integration into existing network (did anyone mention Cisco 7600 load balancing).
