Interesting that SConfig was added. I just script network changes - it's not that difficult if one is organized and methodical, and the commands are well-documented and blogged. We require it for change control anyway. At our shop, complaints about Core network configuration are due only to laziness. 
On remote Server Manager, I didn't catch if that's an RSAT update or available from 2008 R2 only. I'm too lazy to research that!
