Once the 8.1 RTM is available for the Surface 1's, I will be interested to see if this works as advertised. The UI you have in the screen shot is not very different from the options in the current 8.0 or 8.1 Preview screens.
Given that it is clearly documented that Microsoft that RT's VPN client requires an IT admin to permit standard PPTP, L2TP/IPsec, or IKEv2 connections so that a custom VPN client is not required, I'm still not sure what to think here.
Someone comment from Microsoft on any changes or improvements to RT VPN capability, especially as it pertains to VPNs that have required vendor clients previously, would be helpful here.
